Select the most appropriate ANTONYM of the highlighted word. "The enemy, even if it is a child, is a challenge and needs to be removed from his path."

Correct option is B

Explanation of the Correct Answer: · The word "challenge" means an obstacle, problem, or difficulty.
· The antonym should indicate something that solves or removes the difficulty.
· "Solution" is the best opposite, as it means an answer to a problem.
Why Are the Other Options Incorrect? · (a) Problem → Incorrect; a synonym, not an antonym.
· (c) Nuisance → Incorrect; means an annoyance, not a solution.
· (d) Threat → Incorrect; challenge and threat are similar, not opposite.
Thus, the correct answer is (b) Solution.
