The policeman stopped him for jumping the red light but let him out. A. let him off B. let him through C. let him by D. No improvement

let him off
let him through
let him by
No improvement

The correct answer is A. let him off.

The policeman stopped the man for jumping the red light, but he did not give him a ticket. Instead, he let him go. This is an example of the verb “let off,” which means to forgive or excuse someone from a punishment.

The other options are incorrect because they do not convey the same meaning. Option B, “let him through,” means to allow someone to pass through a barrier or obstacle. Option C, “let him by,” means to allow someone to pass by without stopping. Option D, “No improvement,” is incorrect because the sentence is already grammatically correct.
