A) is
B) are
C) am
D) be
Answer: A) is
Explanation:
The correct sentence is:
There is a book on the table.
“Book” is singular, so we use “is” with singular nouns.
“Are” is used for plural nouns(e.g., There are books on the table.)
“Am” is used only with I (e.g., I am happy.)
“Be” is the base form, not used here.
Rule:–There is+ singular noun
There are + plural noun
