B Correct answer
Explanation

The rat kangaroo (or kangaroo rat, Dipodomys spp.) is a desert rodent that can survive its entire life without drinking free water. It obtains all necessary water from metabolic processes (cellular respiration produces water) and from the seeds it eats. Its highly efficient kidneys concentrate urine to minimize water loss, and it is nocturnal to avoid daytime heat. None of the other animals listed have this extreme water independence.
