The forest tracts of the Khasi and Jaintia Hills of Meghalaya are examples of sacred groves which are protected and conserved by local communities due to their association with esteemed places of worship. Thus, statement I is false.
National parks are areas that are rich in biodiversity and are meant for on site conservation of the flora (plants) and fauna (animals) of that region in their natural habitat. These areas are protected by the national government and do not allow any habitat manipulation activities such as forestry, grazing, cultivation, etc. It only allows tourism and research activities with permission. Thus, statement II is true.

Minor human activities such as collection of forest products (timber, food) and research activities are permitted. Thus, statement III is false.
