Which of the following characteristics is associated with amyotrophic lateral sclerosis (ALS)?

Correct answer is C. Amyotrophic lateral sclerosis (ALS), also known as motor neurone disease (MND) or Lou Gehrig’s disease in the United States, is a rare and terminal neurodegenerative disease that results in the progressive loss of motor neurons controlling voluntary muscles. It primarily affects nerve cells in the brain and spinal cord, leading to muscle weakness, atrophy, and eventual paralysis.
