For a formula to evaluate to true when the stage is set to "Negotiation/Review" and the close date is less than one week away, the correct formula is:
* Option B. This formula uses the ISPICKVAL function to check the text value of a picklist and compares the CloseDate to a week from today:
AND( I AND(
ISPICKVAL(StageName, "Negotiation/Review"),
CloseDate - 7 < TODAY()
)SPICKVAL(StageName, "Negotiation/Review"), CloseDate - 7 < TODAY() )
This formula checks that both conditions are met: it confirms the stage name is "Negotiation/Review" and that the CloseDate is within the next 7 days from the current date.
Option A lacks the ISPICKVAL function necessary for evaluating picklist fields. Option C uses DAY(7) which is not a valid Salesforce formula expression. Option D also uses DAY(7) incorrectly and fails to use the ISPICKVAL function.

The feature that the app builder should use to create easy access to the document is a custom detail page link on the Contract object. A custom detail page link is a type of custom button or link that can display a URL or execute JavaScript when clicked. The app builder can create a custom detail page link on the Contract object that displays the pricing guidelines document in a new window or tab. Option A is incorrect because a quick action on the Contracts object is not suitable for this requirement, as quick actions are used to create or update records, log calls, send emails, or launch flows. Option B is incorrect because a quick action on the Account object is not suitable for this requirement, as quick actions are not related to the Contract object. Option C is incorrect because a custom detail page link on the Account object is not suitable for this requirement, as custom detail page links are not related to the Contract object.

Related record and Tabs. These are correct because the related record component allows service agents to view and edit fields from a related record on the same page, and the tabs component allows service agents to switch between different views of related lists or other components on the same page.

The recommended solution to grant the customer service agent access to the field is creating a permission set that allows read-only access to the field via Field Level Security and assigning it to the agent. A permission set is a collection of settings and permissions that give users access to various tools and functions. Field Level Security (FLS) is a setting that controls the access level of fields for different profiles or permission sets. The app builder can create a permission set that grants read-only access to the custom field on the account object via FLS and assign it to the agent. Option B is incorrect because creating a new profile to allow for read-only access to the field via FLS and assigning it to the agent is not recommended, as profiles are used to define the baseline permissions and settings for a group of users, and creating multiple profiles for individual users can be hard to maintain. Option C is incorrect because updating the Customer Service Profile already assigned to the agent to allow for read-only access to the field via FLS is not recommended, as this will affect all users who have the same profile, which may violate the security policy. Option D is incorrect because updating the custom field's FLS in setup to allow the agent read-only access to the field is not possible, as FLS can only be set at the profile or permission set level, not at the user level.
