Have one's hands full means be very busy. 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: Have one's hands full can refer to a situation involving be very busy.
• Story example: A writer may use Have one's hands full when describing a situation involving be very busy.
• Exam example: When a sentence contains Have one's hands full, choose the meaning “be very busy.”
