Arthropods periodically shed and discard their exoskeletons as they grow in a process called

Response:

Choice B

Clarification:

Moulting, or ecdysis, is a procedure that occurs in arthropods, where these creatures replace their existing skeletons to accommodate growth. This process is vital since these invertebrates possess an outer skeleton, which prohibits constant growth; hence, they must molt to develop a new one.

Despite its rigidity, their movement is facilitated by joints. This characteristic led to the naming of the phylum Arthropoda, meaning "articulated feet." Interestingly, discarded exoskeletons can often be found in the environment, resembling strips of bark.
