In the original sentence, the phrase "make two ends meet" is used incorrectly. This phrase typically means managing with limited resources or income to cover expenses. However, it doesn't convey Jatin's feelings of anxiety or nervousness about performing in front of the judges. The correct phrase that would better convey Jatin's nervousness is "get cold feet," which means suddenly feeling too frightened to do something you had planned to do. This replacement emphasises Jatin's apprehension about the upcoming audition and aligns better with the context of feeling nervous before a performance. Therefore, option (a) is the correct choice.
Option (b) does not accurately convey the sense of nervousness or anxiety that Jatin is experiencing. "Cut corners" typically means to do something in a hasty or incomplete manner to save time or effort, which doesn't fit the context of the sentence.
Option (c) is unrelated to the context of the sentence. "Burn bridges" means to destroy relationships or connections with others. This is not related to the context of the sentence.
Option (d) is also unrelated to the context. "Add fuel to the fire" means to exacerbate a problem or situation, which doesn't relate to Jatin's feelings of anxiety about the audition.
Hence, (a) is the correct answer.
The correct sentence is: As the audition approached, John began to get cold feet about performing in front of the judges.
