To flog a dead horse
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. To waste one’s energy on a lost cause.
The idiom 'to flog a dead horse' means:
To keep trying to do something that has no chance of success, or to continue discussing or pursuing a matter that is already settled or hopeless.
In simple terms, it's like putting effort into something that’s already over or pointless — just like beating a dead horse, which obviously won’t respond.

Option 1: To achieve something easily
Incorrect — This would be the opposite of the actual meaning.

Incorrect — The idiom does not refer to anything being valid or ongoing.
Option 4: To escape from the situation
Incorrect — The idiom doesn’t imply running away or escaping.
