In contrapositive method to prove statement “If p then q” is valid

1.	In contrapositive method to prove statement “If p then q” is valid or not, we assume p to be __________ and prove q to be ______________(a) true, false(b) true, true(c) false, false(d) false, trueThis question was addressed to me in a national level competition.I'd like to ask this question from Mathematical Reasoning in division Mathematical Reasoning of Mathematics – Class 11
Answer» Right OPTION is (C) FALSE, false To explain I would SAY: In contrapositive method, we assume p to be false and use it to prove that q is also false. There is no case for p to be true in direct method.
