Question number: 1
Correct option: C
Explanation: The correct answer is “for” because the phrase “frightened for one’s life” is a fixed expression meaning extremely scared about survival. The other options don’t fit this context: “at” suggests a reaction to something visible, “of” implies a general fear, and “about” is more casual.
Question number: 2
Correct option: D
