Question

Fill in the blank with the most appropriate word.
A: Must I always pay my rent by cheque?
B: No, ________ . Pay it however you want to.

• A. you needn't
• B. you mustn't
• C. you shouldn't
• D. you oughtn't

Answer 1

The correct option is A you needn't

• "Needn't" is used to talk about an action that was done but was unnecessary. As the context refers to the action (payment of rent by cheque) that is unnecessary, but can also be done, this is the correct answer.
  "Mustn't" is used say what is definitely unnecessary and to give orders to ourselves or other people.
  "Shouldn't and ought n't", on the other hand, are more like pieces of advice.
  Thus, option A "you needn't" is the correct answer.
