Question

Which option best summarizes the following lines from the passage:
This divergence in response to evolution is commonly expressed by altering the form and function of some part(s) of the organism, the original identification of which is clearly discernible. For example, the creeping foot of the snail is seen in related marine pteropods to be modified into a flapping organ useful for swimming and is changed into prehensile arms that bear suctorial disks in squids and other cephalopods. The limbs of various mammals are modified according to several different modes of life -for swift running (cursorial) as in the horse and antelope, for swinging in trees (arboreal) as in the monkeys, for digging (fossorial) as in the moles and gophers, for flying (volant) as in the bats, for swimming (aquatic) as in the seals, whales and dolphins, and for other adaptations.

• A. Evolution has resulted in the divergence of parts of animals. For example, the creeping foot of the snail is found as flapping organs in marine pteropods and prehensile arms in cephalopods. The limbs of mammals are modified according to the mode of life of the animal.
• B. Parts of animals may change due to divergence resulting from evolution, depending on specific modes of life and function.
• C. Different animals have different parts depending on their mode of life and function of the organ/part.
• D. Evolution has created diverse animals due to adaptation and divergence.

Answer 1

The correct option is B Parts of animals may change due to divergence resulting from evolution, depending on specific modes of life and function.
