Which among the following is a Modus Tollens? Composes a conditional statement, a second premise that asserts the antecedent of the first premise, and a conclusion that asserts the consequent. Consists of one conditional premise, a second premise that denies the consequent of the conditional premise, and a conclusion that denies the antecedent. Consists of two premises and one conclusion. All are hypothetical statements.
