Choose the correct meaning of the given idiom/phrase.
“In a jam”
A. Someone who’s bad.
B. In trouble.
C. A hindrance.
D. An eatable.

Hint:Meaning of In a Jam refers to the difficult situation in which someone got stuck. An idiom/phrase is a form of expression natural to a language.

Complete answer:
Option (A) ‘Someone who’s bad’: is an incorrect option because it refers to some person who doesn't possess a good nature or it might be for someone who’s not in a good shape which is not the same as the meaning of ‘In a Jam’ which shows a situation.
Option (B) ‘In trouble’: is the correct option because it shows the difficult situation or unwanted condition in which someone got stuck which is quite similar to the meaning ‘In a jam’. For example: “The previous action of him brings his friend Ramesh in trouble” which means that the situation got difficult for Ramesh by his friend due to his last action.
Option (C) ‘A hindrance’: is an incorrect option because it refers to the obstacle in someone’s path which can be a part of the situation but not the actual situation.
Option (D) ‘An eatable’: is an incorrect option because it refers to a particular eatable item which one can buy from a store, not the situation which is unpredictable to occur.

Hence the correct answer is option ‘B’.

Note:Whenever a question asks about the idiom it means the figurative language which best suits in a particular situation.
