Explanation:

Prachand Light Combat Helicopter (LCH)

• The indigenous LCH designed and developed by Hindustan Aeronautics Limited (HAL) was formally inducted into the Indian Air Force (IAF) at the Jodhpur Air Force Station. 

• It is capable of destroying enemy air defence and conducting counter insurgency strikes.

• It is the only attack helicopter in the world which can land and take off at an altitude of 5,000 meters.

• The LCH has been designed as a twin-engine, dedicated combat helicopter of 5.8-ton class and categorised as light.

• India has been operating sub 3 ton category French-origin legacy helicopters, Chetak and Cheetah, made in India by the HAL.

• These single engine machines were, primarily, utility helicopters.

Hence only statement 1st is correct.
