If p then q statement is false only when p is true and q is false. In all other cases this statement is true


(A) As '3+3=7^{\prime} is false and '4+3=8^{\prime} is false     so (A) is True
(B) As' 5+3=8^{\prime} is true and 'earth is flat' is false, so     (B) is false.
(C) As 'both (A) and (B) are true' is false (as (B) is false)     and   ' 5+6=17^{\prime} is false so (C) is True.

So, (A) and (C) are true and (B) is false.

Hence option (2) is correct.
