Question

precocial offspring are:
born helpless
born in trees
born underwater
born with feathers and able to walk

Explanation:

Precocial offspring are those that are relatively mature and mobile from birth. Among the options, "Born with feathers and able to walk" fits this definition (e.g., precocial birds like chickens are born with feathers and can walk shortly after hatching). The other options: "Born helpless" describes altricial offspring, "Born in trees" and "Born underwater" are not defining traits of precocial offspring.

Answer:

D. Born with feathers and able to walk (assuming the options are labeled A - D as A. Born helpless, B. Born in trees, C. Born underwater, D. Born with feathers and able to walk)
