@ Sarita, Rashmi, Malini,

Correct answer is D

Hi Kiran,

To exercise p + q > 100 & p > 50

I have considered these values.
1) p = 40, q = 50
2) p = 50 , q = 60
3) p = 60, q = 40
4) p = 60, q = 50

that's how i concluded it to be option a.

Hi Mohan ...

Thanks for explaining this ........ I gave the answer as per ISTQB .....

"100% decision coverage always means 100% statement coverage" -- that's true ...

But Decision coverage measures the coverage of conditional branches and Branch coverage measure both conditional and unconditional branshes.

And at 100% coverage they will exactly the same results
