Correct answer: A. Grow larger in size

  • A. Grow larger in size
  • B. Protect against enemies
  • C. Allow diffusion of gases
  • D. Prevent from desiccation

Explanation

Arthropods need to molt, or shed their exoskeleton, because the rigid structure does not allow for growth. This process, known as ecdysis, enables them to grow larger in size. While the exoskeleton provides protection and helps in preventing desiccation, these are not the reasons for molting. Gas exchange occurs through other specialized structures and is not a reason for shedding the exoskeleton.
