Choice A correctly defines a function named Square that receives an integer input value and returns the integer square of that input value using the mathematical formula intNum * intNum. This is the simplest and most appropriate way to define a function for computing the square of an integer.

Option B is incorrect because it does not include the "As Integer" statement after the function name, which is required to indicate the type of value being returned.

Option C is incorrect because it uses a data type of Double for the return value, which is unnecessary and potentially confusing if the user expects an integer result.

Option D is incorrect because it unnecessarily creates a new variable (dblAns) to store the result before returning it, which adds complexity without any benefits.
