Solution

The correct option is A (a) Only 1 and 2           

The Leatherback turtle is a critically endangered species. The Leatherback Turtle (Dermochelyscoriacea) is the largest of the living sea turtles, weighing as much as 900 kg. Adult leatherback turtles are excellent swimmers. They swim an average of 45-65 km a day, travel upto 15,000 km per year and can dive as deep as 1200 m. Jellyfish is their primary food. Great Indian Bustard, Siberian Crane, Red-headed Vulture and Forest Owlet are also listed under critically endangered birds. Among animals, Pygmy Hog, Kondana Rat and The Sumatran Rhinoceros are listed as critically endangered.
The population spikes of leatherbacks coincide with abundance of jellyfish, making them important top-predators in marine environments. Habitat: Tropical and subtropical oceans. Distribution: Found in tropical and temperate waters of the Atlantic, Pacific, and Indian Oceans. Threats: high Sea fishing operations, harvesting of eggs, destruction of nests by wild predators and domesticated species such as cats, dogs and pigs. Artificial lighting disorients hatchlings and adults and causes them to migrate inland rather.
