Answer : 3. "physical"
Explanation :

Palpable means able to be touched or felt, but it doesn't directly relate to abuse.

Visible means able to be seen, which might not always be the case with abuse.

Intangible means unable to be touched or grasped, which is the opposite of what abuse typically entails.

"Physical" abuse is the correct choice as it directly describes the type of abuse experienced. It refers to any form of abuse that involves physical harm or injury inflicted upon a person.
