Finish the pet owner's funny text message to their friend. Select the grammatically correct option.

My dog Buster loves playing in the mud all day, but he is absolutely afraid of _____ a bath.

The correct answer is taking.

When we use the adjective "afraid" followed by the preposition "of", any verb that comes next must be a gerund (the "-ing" form). So, "afraid of taking" is the correct choice!
