Fill in the blank with the most appropriate option in the following sentence:-

Though Sharon complained and cried bitterly, Mom did not _____ on her.

let off

The correct answer is Option (2) → let off

“Let off” means to excuse someone, to release them from punishment, or to not enforce a consequence.

In the context of a child who is complaining and crying, saying Mom "did not let off" implies that she did not excuse Sharon from the rule, responsibility, or strictness (the pressure) she was imposing.

Note: Given answer is as per NTA. However, let up could also be an answer for this question.  “Let up” means to become less strict, less severe, or to relent.  The sentence means: Even though Sharon cried and complained, Mom did not relent or become less strict.
