Best answer
The correct choice is (b) two times

Easiest explanation - setjmp() macro returns twice. First time, setjmp() returns zero on its direct invocation. Second time macro returns when longjmp is called with the information written to the environment; now, it returns the value passed to longjmp as second argument.
