My complaint is.
Littering on the beach. Too many people just throw their trash on the beach for someone else to clean up. Well no one will clean it up.It gets washed into the ocean where sea creatures can get to it. Then come along some innocent dolphins interested on whats lying in the ocean. They start playing with it and suddenly they get trapped in the trash. they could get badly hurt or even die. Just from people littering. So please any one whose reading this if you go to the beach any time soon. Don't litter and clean up other trash you see lying around.
I believe you have a typo when it comes to the first option - it should be athletics, not athletic. The word athletic is an adjective, and the word athletics is a noun.
That being said, the correct answer is A. athletics. Even though this noun ends in -s, it is still singular. The rest of the options are all plural nouns.
