The correct answer is: B) Indian Roller.
The Indian roller is a large, brightly colored bird that is found in open country and scrubland in India, Pakistan, Sri Lanka, and Nepal. It is the state bird of Karnataka.
The Indian roller is a member of the roller family, Coraciidae. Rollers are medium-sized to large birds with long, pointed wings and short tails. They have brightly colored plumage, often with iridescent feathers. Rollers are known for their acrobatic flight displays, which often include tumbling and somersaulting.
The Indian roller is a resident bird in most of its range, but some populations may migrate to lower elevations in winter. It is a common bird in open country and scrubland, where it feeds on insects, reptiles, and small mammals. The Indian roller is a monogamous bird, and pairs build their nests in trees or bushes. The female lays two to three eggs, which hatch after about 18 days. The young birds fledge after about 21 days.
The Indian roller is an important part of the ecosystem, as it helps to control insect populations. It is also a popular bird with birdwatchers, due to its beautiful plumage and acrobatic flight displays.
