Identify the grammatically correct sentence below:

a. These is good crackers.

c. These apples ain't got no fat.

b. Johnny is the baddest guitar player.

d. Those pencils are going to fall.

The correct answer is d. Those pencils are going to fall.

The first sentence doesn't agree the subject and the predicate; the second sentence should use the "don't have any fat"; the third sentence uses baddest which is incorrect grammatically.
