Question

Which part of the letter needs revision in order to be

appropriate for a formal letter?
the salutation
the body
the closing
the signature

Answer 1

the body of the letter

Step-by-step explanation:

the body of a formal letter is different from an informal letter. the introduction of a formal letter should be direct and free from familiarity.

the body should state the essence of the letter and it should be free from informal expressions. no shortened words are expected here e.g. isn't , etc.
