Choose which part of the sentence has an error:- A. Inspite of his po…

The correct answer is Option (1) → A

In spite of + noun:

• In spite of is written as three words. "Inspite" is not a word.
• Like any preposition, it is followed by a noun or noun phrase, not by an adjective alone.
• This sentence: "popular" is an adjective with no noun after it, so it should be the noun popularity.
  Corrected: In spite of his popularity, he cannot be called a great writer and orator.
  Example: In spite of the rain, the match went on.

A. Inspite of his popular — Error.

• It should read In spite of his popularity.

B. he cannot be — No error.

• The modal cannot is followed by the base form "be".

C. called a great — No error.

• "Be called" is the correct passive form after a modal.

D. writer and orator — No error.

• One article "a" for writer and orator is correct, since both nouns describe the same person.
