The GetCurrentRate method retrieves the current interest rate and a variable named currRate that stores the current interest rate. You have to write a code segment. When an instance of the class is deserialized, the code segment updates the currRate variable with the current interest rate. In the options below, which code segment should you use?

• A.[OnSerializing]internal void UpdateValue (StreamingContext context) { currRate = GetCurrentRate();}
• B.[OnDeserialized]internal void UpdateValue(StreamingContext context) { currRate = GetCurrentRate();}
• C.[OnDeserializing]internal void UpdateValue(SerializationInfo info) { info.AddValue("currentRate", GetCurrentRate());}
• D.[OnSerializing]internal void UpdateValue(SerializationInfo info) { info.AddValue("currentRate", GetCurrentRate());}
