Fill in the blank in the sentence given below by choosing the correct option.
You should be sure that he won’t ________ his word.

Correct option is B

The correct option to fill in the blank is (b) go back on.
Explanation of correct answer:
· The phrasal verb “go back on” means to break a promise or fail to keep one’s word
· (वादा तोड़ना).
· The sentence talks about keeping a promise, so this phrasal verb fits both grammatically and contextually.
Example:
A good leader never goes back on his word.
Why other options are incorrect:
· (a) put up with – tolerate (सहन करना), contextually incorrect.
· (c) put out of – remove or inconvenience (असुविधा देना), incorrect usage.
· (d) run away with – steal or take impulsively (ले भागना), wrong meaning.
