Explanation:

Both statements are incorrect.

• Eco-Sensitive Zones – ESZ is fragile areas around protected areas, they are notified under Section 3 of Environment Protection Act 1986 by  the Ministry of Environment, Forest, and Climate Change (MoEFCC). 

• The purpose of declaring ESZs is to create some kind of “shock absorbers” to the protected areas by regulating and managing the activities around such areas. As per the National Board for Wildlife NBWL, the delineation of eco-sensitive zones have to be site-specific, and the activities should be regulative in nature and not prohibitive unless required.

Hence option 4th is correct.
