CORRECT ANSWER IS -
A: Triggers that create records represent the Model (M) part of the MVC framework.
B: Validation rules enforce business rules and represent the Controller (C) part of the MVC framework

Explanation Why Correct:
A: Triggers in Salesforce are part of the Model because they deal with the data manipulation logic that occurs in the database layer.

B: Validation rules act as a part of the Controller because they enforce business logic and determine what data can be saved in the Model.

INCORRECT OPTIONS:
C: This is not correct because Standard and Custom objects represent the Model (M) part of the MVC framework, as they are the data structure.

D: This is incorrect because Lightning component HTML files represent the View (V) part of the MVC framework, as they define the user interface.
