Question

Fill in the blank with the suitable option:
Once he has signed the agreement, he won’t be able to ______________.
A) Back up
B) Back in
C) Back at
D) Back out

Answer 1

Hint: Vocabulary plays an important role and it is very essential to understand the meaning of the words given in the options. So, understand the sentence and fill the blank with the most suitable word.

Complete answer:
Let us look into the given options:
Option A) Back up – is an incorrect answer because the meaning of backup is ‘provide support for something or for someone’. For example: Her mother backed him up for everything. This option is not best fit in the sentence because the first part of the sentence says that he has signed an agreement and he won’t be able to provide support does not go well in the sentence. Therefore, this is an incorrect answer.
Option B) Back in – is an incorrect answer because the meaning of back in is ‘reverse’. For example: Back in the day, we had an apartment with a swimming pool. This option is not best fit in the sentence and does not go well in the sentence. Therefore, this is an incorrect answer.
Option C) Back at – is an incorrect answer because the meaning of back at is ‘used to return a greeting or insult’ and this is completely incorrect when to fill the blank because it makes the sentence meaningfully incorrect ‘Once he has signed the agreement, he won’t be able to back at’. Therefore, this is an incorrect answer.
Option D) Back out – is the correct answer because the meaning of back out is ‘withdraw from a commitment’ and this is the best fit in the sentence as it states that he has signed the agreement and he cannot withdraw from this. Therefore, this is the correct answer and makes the sentence meaningfully correct.

Thus the correct answer is option ‘D’.

Note: Back out defines something that you have decided not to do something that you previously agreed to do. For example: You agreed to come but you can’t back out now. So, as per the sentence given in the question back out suits the best.
