Assume that a program creates and initializes a Short Integer variable named age and a pointer named agePtr, to which it assigns the address of the age variable. Which of the following statements will assign the number 21 to the age variable?

The correct answer is: A. age = 21;

Option A assigns the number 21 to the age variable.

Option B assigns the number 21 to the memory location pointed to by the age variable. This will not change the value of the age variable itself.

Option C assigns the address of the age variable to the agePtr pointer. This will not change the value of the age variable itself.

Option D assigns the number 21 to the memory location pointed to by the agePtr pointer. This will not change the value of the age variable itself.

Option E is incorrect because it includes both Option A and Option D. Option A is the only option that will assign the number 21 to the age variable.
