Complete the code for the calcPower recursive method shown below, which is intended to raise the base number passed into the method to the exponent power passed into the method:
public static int calcPower(int baseNum, int exponent)
{
int answer = 0;
if (exponent == 0)
{
answer = 1;
}
else
{
_______________________________________
}
return answer;
}
A) answer = baseNum * calcPower (baseNum -1, exponent);
B) answer = baseNum * calcPower (baseNum, exponent - 1);
C) answer = baseNum * calcPower (baseNum, exponent);
D) answer = baseNum * calcPower (baseNum -1, exponent - 1);

To raise a number to a power, we need to multiply the base number with itself exponent times. In each recursive call, we reduce the exponent by 1 until we reach the base case where the exponent is 0. At that point, we return 1 since any number raised to 0 is 1. In the recursive step, we multiply the base number with the result of the recursive call with the exponent reduced by 1. Therefore, the correct line of code is "answer = baseNum * calcPower(baseNum, exponent - 1);".
