Question

Manoj Kumar · Accepted Answer

Final Answer : C, Explanation :  This is a deductive argument because it makes use of the logical principle of modus tollens, which involves denying the consequent of a conditional statement. It begins with a conditional premise (if robbery had been the motive, the money would have been taken) and then denies the consequent (the money was not taken). Therefore, it concludes that the antecedent is also false (robbery was not the motive). This argument is deductively valid, meaning that if the premises are true, the conclusion follows necessarily.
