a. this fatal disease leads to severe and progressive memory loss.
b. this fatal disease attacks the peripheral nervous system.
c. this nonfatal disease is characterized by severe memory loss.
d. this nonfatal disease disrupts the central nervous system (cns).

please select the best answer from the choices provided.

☐ a
○ b
☐ c
○ d

Explanation:

To solve this, we analyze each option:

• Option A: Multiple sclerosis is not fatal, and memory loss is not its main feature (Alzheimer's is more associated with memory loss). Eliminate A.
• Option B: Multiple sclerosis affects the central nervous system (CNS), not the peripheral nervous system. Eliminate B.
• Option C: Multiple sclerosis is non - fatal but is not characterized by severe memory loss. Eliminate C.
• Option D: Multiple sclerosis is a non - fatal disease that disrupts the central nervous system (CNS) by damaging the myelin sheath around nerve fibers. This matches the correct description.

Answer:

D. This nonfatal disease disrupts the central nervous system (CNS).
