In the game, which option would require multiple participants to perform on you simultaneously on your backside?

• A. Lick the toilet bowl.
• B. Let the person next to you wax you wherever they want.
• C. Let another player throw flour in your face.
• D. Let each person in the group slap you as hard as they can on your butt.

Answer: (D)

This item tests recognizing a scenario where more than one participant acts at the same time on a single area of the body. The correct choice describes every person in the group delivering a slap to your butt at the same moment, which satisfies both multiple participants and simultaneous action on the backside. The other options involve either a single person performing an action or actions not focused on the backside (or not happening simultaneously by the whole group), so they don’t meet the specified condition.
