Select the word segment that substitutes the bracketed word segment correctly and completes the sentence meaningfully. Select ‘No correction required’ if the sentence is correct as given.

Nine men's morris is a strategy board game for two players (dated) at least to the Roman Empire.

The error lies in the bracketed word, and the correct replacement is option (a).

• Explanation: The structure requires a present participle to show origin/time connection: “a game … dating at least to the Roman Empire.”
• “Dated” is incorrect here because it does not properly function as the modifier of the noun phrase in this context.

Grammatical rule (English):

• Use present participle (V + ing) to modify a noun and show continuing relevance: “a game dating back …”.

व्याकरण नियम (Hindi):

• किसी वस्तु के पुराने समय से जुड़े होने को दिखाने के लिए V+ing (dating) का प्रयोग किया जाता है।

So the correct answer is (a)
