Statement 1 and 2 are correct. The Olive ridley turtles are the smallest and most abundant of all sea turtles found in the world, inhabiting warm waters of the Pacific, Atlantic and Indian oceans. Though found in abundance, their numbers have been declining over the past few years, and the species is recognised as Vulnerable by the IUCN Red list. The coast of Orissa in India is the largest mass nesting site for the Olive-ridley, followed by the coasts of Mexico and Costa Rica.
