The relation between Maru Raikas and camel rearing shows which environmental adaptation?

Correct answer: Camels were useful animals in dry desert areas

The direct answer is A: camels were useful animals in dry desert areas. The Maru Raikas are associated with pastoral life in the arid regions of Rajasthan, and camel rearing suited their environment. Camels can travel long distances in dry conditions and can survive with less frequent water than many other large domestic animals. They were useful for transport and for supporting desert livelihoods. Option A is correct because it links the animal selected by the community with the environmental conditions in which it lived. Option B is wrong because camels are not animals limited to snowy peaks. Option C is wrong because camels do not graze in the sea. Option D is wrong because inability to plough does not make camels useless; their value included transport and adaptation to arid land. The question tests environmental adaptation: communities choose or depend on animals suited to local climate and resources. Memory cue: dry desert conditions make camel rearing practical.
