Explanation:

Only statements 1&2 are correct.
Features of UDAN 5.0

• There is no restriction on the distance between the origin and the destination of the flight. 

• VGF to be provided will be capped at 600 km stage length for both Priority and Non-Priority areas; earlier capped at 500 km.

• No predetermined routes would be offered; only Network and Individual Route Proposal proposed by airlines will be considered.

• The same route would not be awarded to a single airline more than once, whether in different networks or in the same network.

• Airlines would be required to commence operations within 4 months of the award of the route; earlier this deadline was 6 months.
