Answer:
A. A
Read Explanation:
When the subject of a sentence is a compound subject (in this case, "a pen and a pencil"), the verb should agree with the plural subject. Here, the compound subject "a pen and a pencil" requires a plural verb.
Error: "There is" should be "There are" because the subject is plural.
Corrected Sentence: "There are a pen and a pencil in the box."
