Shyam wants a pen, but _____ is at home.

  1. She
  2. He
  3. It


Pronouns take place of nouns. This is done because sometimes, we don’t want to repeat the noun again and again. Personal pronouns like ‘he’, ‘she’, ‘they’ are used to replace names of persons. ‘it’ is used to replace things. ‘He’, ‘she’, ‘it’ are used to take place of one person or thing in the subject of the sentence.

The correct answer is: It

    The correct answer is 'it'.
    Shyam wants a pen, but it is at home.
    The pen is a thing which is being replaced by the pronoun 'it' in the second part of the sentence.
