In February, 2023 India's biggest helicopter manufacturing plant was inaugurated inwhich one of the following places?

1. A

   Chakeri, Uttar Pradesh

   Option (a) claims Chakeri, Uttar Pradesh is the site of the new helicopter facility, but this location is associated with other defense and aerospace projects rather than this specific manufacturing unit. It is incorrect because the prime facility was established in the southern part of the country.

2. B

   Tumkuru, Karnataka

   Option (b) asserts that the helicopter manufacturing plant was inaugurated in Tumkuru, Karnataka. This is the correct option because Prime Minister Narendra Modi inaugurated Hindustan Aeronautics Limited's greenfield helicopter factory at Tumkuru in February 2023, making it India's biggest helicopter manufacturing facility.

3. C

   Coimbatore, Tamil Nadu

   Option (C) points to Coimbatore, Tamil Nadu, which hosts a thriving industrial and textile ecosystem but does not house this landmark helicopter unit. It is not the key since HAL's massive new manufacturing plant was set up elsewhere.

4. D

   Nasik, Maharashtra

   Option (d) names Nasik, Maharashtra, an established hub for HAL operations and aircraft overhauling. However, it is incorrect in the context of the specific February 2023 inauguration of India's biggest greenfield helicopter plant.

Summary. Official key is (b) Tumkuru, Karnataka. In February 2023, the country's largest helicopter manufacturing facility was inaugurated by the Prime Minister at Tumkuru in Karnataka. This greenfield helicopter factory was established by Hindustan Aeronautics Limited to boost domestic chopper production. Other options like Chakeri, Coimbatore, and Nasik host various industrial or aerospace units but are not the sites of this specific record-setting plant. Therefore, option (b) is the correct choice.
