Final Answer :
C
Explanation :
The probability of having a male (M) or female (F) child is 1/2 for each child. The scenarios where only one child is male are: MFF, FMF, and FFM. Each of these scenarios has a probability of (1/2)^3 = 1/8. Since there are three such scenarios, the total probability is 3 * 1/8 = 3/8.
