Hint: A frog is any member of a large species of short-bodied, tailless amphibians, mostly carnivorous.

Complete Answer:
- In general, frogs are known as excellent jumpers and the greatest jumpers of all vertebrates, according to their size. Litoria nasuta, the striped rocket frog, can leap over 2 metres (6 feet 7 in), a distance that is more than fifty times its body length of 5.5 centimetres (2.2 in).
- There are considerable variations in jumping potential between species. Inside a population, with increasing height, jump distance increases, but relative jumping distance (jumped body-lengths) decreases.
- The Euphlyctis cyanophlyctis (Indian skipper frog) has the ability to jump from a position floating on the surface outside the water. In a series of quick fast leaps, the tiny northern cricket frog (Acris crepitans) will'skitter' over the surface of a pond. Slow-motion imaging reveals that there is passive versatility in the muscles.
- When the frog is already in the crouched state, they are first extended, then they are contracted before being extended again to propel the frog into the air.

So the answer is “Option C”.

Note: For the remainder of the jump, the forelegs are crossed against the chest and the hind legs stand in an extended, sleek posture. The peak strength exerted during a leap will surpass that which the muscle is technically capable of generating in certain highly capable jumpers, such as the Cuban tree frog (Osteopilus septentrionalis) and the northern leopard frog (Rana pipiens). The energy is then passed into the extended tendon, which is wound around the ankle joint, as the muscles contract. And, at the same time as the tendon sheds its energy like a catapult, the muscles expand again to create a strong acceleration above the limits of acceleration driven by muscle. In locusts and grasshoppers, a related mechanism has been documented.
