Correct option is B
The correct option to fill in the blank is (b)
banned.
Explanation: “Has banned” is the
present perfect form (has + V3) indicating a completed action with present relevance—here, the policy has
imposed a prohibition. “Ban” means to
prohibit/forbid something officially (Hindi:
प्रतिबंध लगाना/निषेध करना). Thus, “The new policy has banned the use of plastic bags” is grammatically precise and contextually apt.
Example: The government has banned single-use plastics across several cities.
Explain why other options are incorrect.
·
(a) bond — tie or join together; a connection (Hindi:
बंधन/संबंध). Not a verb of prohibition.
·
(c) bend — curve/turn from a straight form (Hindi:
झुकाना/मोड़ना). Meaning mismatch.
·
(d) band — a group or a strip; also a verb “to band together” (Hindi:
दल/पट्टी; समूह बनाना). Not used for prohibiting.
