The order of execution when a Case record is saved in Salesforce is as follows:
* Validation Rules: These are processed first to ensure that all data meets the validation criteria before any further processing occurs.
* Assignment Rules: After validation, assignment rules determine the ownership of the case based on the criteria defined.
* Escalation Rules: These are processed next to escalate the case if it meets certain criteria.
* Auto-Response Rules: Finally, auto-response rules are executed to send automatic responses to case submissions if applicable.
Options A, B, and C do not represent the correct order of execution in Salesforce.

Expected revenue is calculated as Amount x Probability. If the expected revenue field displays incorrect values, it means that the probability associated with the stage is not accurate. The administrator should change the probability to reflect the actual likelihood of closing the opportunity at that stage. References: https://help.

The equals operator is an operator that compares two values and returns true if they are equal or false if they are not equal; it can be used in decision elements in flow builder to check if two values match certain criteria.
The {!$GlobalConstant.True} value is a global constant value that represents true in flow builder; it can be used in decision elements in flow builder as one of the values being compared. Using equals operator and
{!$GlobalConstant.True} as value can help Cloud Kicks update screen flow so that if checkbox field High Value Customer is set true first screen is skipped by using equals operator compare High Value Customer field value with {!$GlobalConstant.True} value in decision element output connector conditions; if condition is met first screen is skipped else first screen is shown. Using equals operator "High Value Customer" as value contains operator {!$GlobalConstant.False} as value contains operator "High Value Customer" as value are not valid options for updating screen flow skip first screen if checkbox field High Value Customer is set true because they either use wrong values wrong operators compare checkbox field values.
