Answer:

d. result = cube(4);

Explanation:

Given

Prototype: int cube(int num);

Function: int cube(int num)  {  return num * num * num; }

Required

The statement to get the cube of 4, saved in result

To do this, we have to call the cube function as follows:

cube(4);

To get the result of the above in variable result, we simply assign cube(4) to result.

So, we have:

result = cube(4);
