Pick the odd one out.

Option (a): Soap: A cleaning product used to wash the body.

Option (b): Oil: A substance used for moisturizing or conditioning, but not specifically for cleaning.

Option (c): Shampoo: A cleaning product used for washing hair.

Option (d): Comb: A tool used for grooming and styling hair, not for cleaning.

Comb is the odd one out because it’s not a cleaning product like the others.

Thus, the correct answer is (d) Comb.​
