Select the most appropriate option to fill in the blank.

You ______ carry all the books to school daily.

need not

The most appropriate option to fill in the blank is need not.

The sentence is about the speaker telling the listener that they do not need to carry all the books to school daily. The word "need not" is the most appropriate word to use because it means "not necessary" or "not required". The other options are not as appropriate.

• Have not means "do not possess" or "do not have". This does not make sense in the context of the sentence because the listener does have the books, they just do not need to carry them all to school daily.
• Would not means "did not want to" or "was not willing to". This does not make sense in the context of the sentence because the listener is not refusing to carry the books, they just do not need to do so.
• Ought not means "should not" or "is not right to". This does not make sense in the context of the sentence because there is nothing wrong with carrying all the books to school daily, it is just unnecessary.
