Which of the following refers to computer code, in VBA, that performs some action on or with objects?a.Integrity constraintb.Sub procedurec.Excel Functiond.Primary key

The correct answer is b. Sub procedure.

Here's why:

a. Integrity constraint: This is a rule that helps ensure the quality of information stored in a database by preventing the entry of invalid data. It's not related to performing actions on or with objects in VBA.

b. Sub procedure: In VBA, a Sub procedure is a series of statements enclosed by the Sub and End Sub statements. The code inside a Sub procedure performs actions on or with objects. It can be called multiple times and can be triggered by an event or called by other procedures.

c. Excel Function: While Excel functions can be used within VBA, they are not specific to VBA and do not necessarily perform actions on or with objects.

d. Primary key: This is a term used in databases. It's a unique identifier for a record in a database table. It doesn't refer to computer code in VBA that performs some action on or with objects.
