In bad faith means dishonestly or without sincere intention. 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 bad faith can refer to a situation involving dishonestly or without sincere intention.
• Story example: A writer may use In bad faith when describing a situation involving dishonestly or without sincere intention.
• Exam example: When a sentence contains In bad faith, choose the meaning “dishonestly or without sincere intention.”
