Hint:A whole new family of limbless amphibians has been found, hidden in the soils of northeastern India. Organisms are part of the Caecilian order of amphibians, that look very much like earthworms than frogs or toads, and may evolve to more than a metre in length.

Complete Answer:
Salamanders are usually short-bodied, four-legged, moist-skinned creatures, around 10 to 15 cm in length. Like all amphibians, they consume water through their skin, and they need a moist environment. In areas where temperatures are below zero, they also hibernate.

These famous Eel are aquatic creatures who have got their title from the tremendous electrical charge they can produce to shock the prey and prevent predators. They live in ponds and feed mainly on fishes, birds and small mammals.

Snakes are lengthened, legless, carnivorous reptiles of the suborder serpentes. Like all other squamates, snakes are ectothermic, amniotic vertebrates surrounded by overlapping scales.

Ichthyophis is a caecilian genus and unusual amphibian. They're limbless amphibians, also named Asian caecilians. They prefer to dwell underwater, burrowing their long , slender bodies into loose dirt and dirt litter. They are limbless amphibians that look like a worm or a snake on the surface. They have small, sensory tentacles between their eyes and noses that help them discover their environments and locate their prey. So, they almost all have features like amphibians.

Rhacophorus is a family of frogs mostly in the shrub frog family. These frogs have long toes and a thick webbing connecting them, allowing the animals to slow down their slide.

Hence the correct option is D, Ichthyophis

Note:In all, seven new varieties of these limbless, soil-dwelling amphibians have been found by a team of researchers who have spent 1,000 man-hours searching. This discovery adds a significant branch to the amphibian family tree.
