Question

Fill in the blank with the most appropriate word.
People are always mistaking him _____ his twin brother.

• A. with
• B. for
• C. about
• D. on

Answer 1

The correct option is B for

A preposition is a word which comes before a noun or a pronoun and establishes a relationship between the elements of a clause or words.

The correct answer is option B) for as 'for' indicates as to what something/ someone is being understood.

'With', 'about' and 'on' can not be used here as with indicates the something's inclusion , 'about' is used to refer information and 'on' is used to indicate the position of something.

'People are always mistaking him for his twin brother.'
