The correct answer is: B. mutator functions
A mutator function is a function that changes the state of an object. For example, a function that sets the value of a variable is a mutator function.
An inspector function is a function that reads the state of an object. For example, a function that returns the value of a variable is an inspector function.
An auxiliary function is a function that supports the main functionality of a program. For example, a function that sorts a list of numbers is an auxiliary function.
A manager function is a function that controls the flow of execution of a program. For example, a function that calls other functions in a specific order is a manager function.
In the given question, the function printDataMembers() is not likely a mutator function because it does not change the state of the object. It is more likely an inspector function because it reads the state of the object.
