Select the most appropriate option to fill in blank no. 5.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e. reward.
Filler Concept: The sentence talks about the positive outcome of efforts made by the government and environmentalists.
Grammatical Explanation:
"Reward" means a result or benefit gained in return for effort, which suits the context perfectly.
"Profit" is commercial and not appropriate here.
"Honour" and "award" refer more to formal recognition or prestige, not the direct outcome of efforts.
Correction: This success is the reward of collective efforts of the government and the environmentalists.
Conclusion: “Reward” best fits the idea of an outcome earned through hard work.
