C. Have a firm grip on branches
D. Catch food on its way

Answer 1

Hint: Kangaroos have powerful hind legs, long, sturdy tails, and short front legs. The kangaroos belong to the Macropus family of animals, literally "big foot." Thanks to their large legs, the kangaroos can hop some 30 feet (9 metres) in one bound and fly more than 30 miles (48 kilometres ) per hour.

Complete Answer:
- When jumping, kangaroos use their strong tails for balance. They are the tallest of all marsupials, taller than 2 metres (6 feet). In Eastern Australia, kangaroos live. They live in small groups ('Mobs' by the Australians) called troops or herds, usually made up of 50 or more animals. The kangaroos will pound the ground with their strong feet in alarm if attacked. Kangaroo fighting is kicking opponents, and sometimes biting. ​
- To cradle baby kangaroos called joeys, female kangaroos carry a pouch on their belly made of a fold in the skin. At birth, or around the size of a grape, newborn raisins are just one inch long (2.5 centimetres).
- When in their lowered grazing role, rather than using their legs, red kangaroos use their tails and forelimbs to raise themselves off the ground as they chew their way through grasslands — comparable to having two legs on a skateboard and a third leg with which to drive forward. But what is much more remarkable is the individual strength of the tail as its own limb, and not just its use as a crutch for walking.
Their tails are more than 20 vertebrae, taking the place of our foot, calf, and thigh.

The correct answer is option(B) Maintain balance.

Note: The propulsive force created by the tail rivals that of the combined front and hind limbs, and the work done by the tail probably helps the animal save energy as it travels between tasty plant patches.
