Correct Answer : A
if is a conditional statement which executes only if the condition is true. For every if statement there need not be an else statement. if can stand independently without else. But for every else there must be an if because control goes to else if-and-only-if condition in if fails. if can also be used inside another if which is called as nested-if.
