Explanation

Option A — Incorrect: ONDC is not based on government-controlled transactions. Its aim is to create an open and decentralized digital commerce ecosystem.

Option B — Incorrect: ONDC does not intend to eliminate private e-commerce platforms. Existing apps and platforms can join the ONDC network and transact with one another.

Option C — Correct: ONDC seeks to democratize digital commerce by moving away from closed, platform-driven marketplaces towards an open and interoperable network. This gives MSMEs, small sellers and local businesses greater access to consumers and reduces dependence on a few dominant platforms.

Option D — Incorrect: ONDC does not require UPI as the mandatory payment mechanism. The comparison with UPI refers mainly to its open-network model, not to compulsory use of UPI.

Therefore, Option C is the correct answer.
