The clock is in front of the CD.                    NO CORRECTIONS


The book is behind the cup.                       NO CORRECTIONS


The steak is next to the pancakes.              NO CORRECTIONS



The cats is under the bed.     CORRECTION:  The cat is under the bed.



EXPLANATION:
Always be reminded of the subject-verb agreement rule regarding to the quantity of the subject should be equal to the verb of the sentence.

"cat" is singular noun or subject therefore the be-verb should be singular as well which is "Is."

"cats" is plural therefore the be-verb should be plural as well which is "are."
