The correct option is B b and c

The Kangaroo rat is almost perfectly adapted to life in the desert. They can survive without even drinking any water, getting needed moisture from their seed diet. They have excellent hearing and can even detect the silent sound of an owl approaching. Their large back legs enable them to jump up to 9 feet in one jump in order to escape predators. Kangaroo rats inhabit a variety of desert niches. These can include open desert scrub, open grasslands, washes, sandy soils or creosote flats. Kangaroo rats have pouches, but not for carrying their babies. Their pouches are on the outside of their cheeks and are used for carrying seeds back to their burrows.
