Final answer:
Both a folded mat and block wedge are correct modifications that can be used to support students with carpal tunnel syndrome, to reduce wrist strain and improve ergonomics.
Step-by-step explanation:
The question is asking about what props or modifications could be used to assist students with carpal tunnel syndrome during activities or in a classroom setting. Answer c, "Both are correct," is the right choice. A folded mat can provide cushioning and support to reduce the strain on the wrists, while a block wedge can be used to elevate the wrists and keep them in a neutral position, which can help alleviate discomfort and improve ergonomic positioning. These modifications are designed to lessen the pressure on the median nerve, which is the primary concern for those with carpal tunnel syndrome.
