The correct answer is: c) Great Hornbill.
The Great Hornbill is a large, colorful bird found in the forests of India and Southeast Asia. It is the official state bird of Kerala, India. The Great Hornbill is a member of the hornbill family, Bucerotidae, which includes about 50 species of birds. Hornbills are characterized by their large, casqued beaks, which are used for display and to excavate nesting holes. The Great Hornbill is the largest hornbill in India, with a wingspan of up to 2 meters. It is a black bird with a white neck and chest, and a large, yellow casque on its beak. The Great Hornbill is a social bird, and lives in groups of up to 12 birds. It is a frugivore, and its diet consists mainly of fruits, but it will also eat insects, small mammals, and birds. The Great Hornbill is a monogamous bird, and pairs mate for life. The breeding season is from January to March, and the female lays 2-3 eggs in a nest hole excavated by the male. The eggs hatch after about 30 days, and the chicks are altricial, meaning that they are born helpless and require parental care. The chicks fledge after about 60 days, and they reach sexual maturity at about 3 years of age. The Great Hornbill is a vulnerable species, and its population is declining due to habitat loss and hunting. It is protected by law in India, but it is still hunted for its meat and its casque, which is used in traditional medicine.
