Newborn cottontail rabbits are born blind, without much fur, and totally dependent on their mothers.

• A. Cannot be determined
• B. True
• C. False
• D. Partly true

Answer: (B)

Newborn cottontail rabbits are altricial: they are blind, born with very little fur, and completely dependent on their mother for warmth and nourishment. This aligns with the defining trait of altricial young, so the statement is true. They don’t open their eyes at birth and aren’t fully furred, and their survival depends on the mother’s care, which is why this is the best answer. The other options don’t fit because the description is neither unknown, nor false, nor only partly true—the characteristics described accurately match newborn cottontails.
