What is the logic behind the sign for 'pig'?

• A. Pigs like to wallow in mud up to their chins
• B. Pigs like to eat corn
• C. Pigs sleep in stalls
• D. Pigs are loud

Answer: (A)

Animal signs often use a visual cue tied to a well-known behavior. For pig, the most recognizable trait is mud-wallowing, so the sign is built to evoke that idea—an action that people instantly associate with pigs. That makes the gesture intuitive and easy to remember, showing why this explanation fits best. The other options describe things pigs do, but they don’t provide the same clear, distinctive cue that defines the sign.
