In the balance means uncertain and depending on what happens next. This answer is correct because the expression has a fixed figurative meaning in English. In an SSC idiom question, students should match the whole phrase with its accepted meaning rather than translate each word separately.

• Classroom example: In the balance can refer to a situation involving uncertain and depending on what happens next.
• Story example: A writer may use In the balance when describing a situation involving uncertain and depending on what happens next.
• Exam example: When a sentence contains In the balance, choose the meaning “uncertain and depending on what happens next.”
