Answer: The correct option is (B) sometimes.
Step-by-step explanation: Given that p and q are statements such that p → q is true.
We are to select the correct option that gives the situations for being q → p true.
We know that
the truth table for p → q and q → p is as follows :
p q p → q q → p
T T T T
T F F T
F T T F
F F T T
Therefore, we can see that if p → q is true, then q → p is sometimes true, not always.
Thus, the complete statement is
If p → q is true, then q → p is SOMETIMES true.
Option (B) is CORRECT.
