Zoological parks are an example of ex situ conservation, while national parks, wildlife sanctuaries, and biosphere reserves protect species in their natural habitats.

Pulling arms closer reduces the moment of inertia (I). With no external torque, angular momentum (L = Iω) is conserved, so ω increases as I decreases. As per NCERT, applying relevant law/formula with correct units and sign convention leads to Due to conservation of angular momentum. This satisfies dimensional consistency and physical conditions given, so option B is scientifically correct.
