Question

Fill in the blank with the most appropriate word.
There isn't ____ at your house now.
A. Person
B. Somebody
C. People
D. Anybody

Answer 1

Hint:The sentence requires an indefinite pronoun to have its meaning completed. Indefinite pronouns do not clearly describe persons or things, but in terms of general and non-specific terms.
Indefinite pronouns are replacement words for objects in English grammar that can not be or are actually not exactly meant to be called. So, instead of them, they can be used, or more specifically, they can 'substitute' them.

Complete answer:
The indefinite pronoun should be singular as indicated by above usage of ‘is’ . The usage of ‘not’ in ‘isn’t’ indicates that the indefinite pronoun should be the one that could be used in a negative sentence.
Thus ‘anybody’ is the correct word.
There isn’t ‘anybody’ at your house.

Lets see other options-
Person :- Given sentence requires indefinite pronoun but ‘person’ is noun thus this option is wrong.
Somebody :- somebody is used in positive sentences but given sentence is negative thus this option is wrong too.
People :- Given a sentence requires indefinite pronouns but ‘people’ is a noun thus this option is wrong.
Anybody :- anybody is used in a negative sentence thus this option is the correct option.

Hence the correct answer is option D.

Note:Generally, indefinite pronouns, which may also be in the plural, refer to individuals or objects. The terms 'some' and 'some' also serve as a basis if this is the case,
Indefinite English pronouns often end in '-body' or '-one' if individuals are referred to. The person to be replaced may then be either male or female. All in all, there are no variations in importance between these two versions.
