The correct response to explain why the size of an organism with an exoskeleton is limited is:
**When the size of the exoskeleton doubles, the weight of the exoskeleton increases by eight times.**
This is because the weight of the exoskeleton (which is a function of volume and density) increases with the cube of the size (i.e., width, length, and height) when the size of the organism increases, while the strength and surface area (which are important for support and movement) increase at a lower rate, specifically with the square of the size. This mismatch creates limitations on the maximum size of organisms with exoskeletons.
