Which of the following conditions is linked to a deficiency in Vitamin C?

The correct answer is Scurvy, which is directly caused by a deficiency in Vitamin C. Vitamin C plays a crucial role in the synthesis of collagen, a protein that helps maintain the integrity of connective tissues, skin, and blood vessels. When an individual does not get enough Vitamin C, symptoms of scurvy can develop, including fatigue, swollen gums, joint pain, and skin problems, due to impaired collagen formation.

Night blindness is associated with a deficiency in Vitamin A, which is essential for eye health and vision. Pellagra results from a deficiency of niacin (Vitamin B3) and is characterized by symptoms like dermatitis, diarrhea, and dementia. Beriberi is linked to a deficiency in thiamine (Vitamin B1) and can affect the cardiovascular and nervous systems, leading to various health issues. Each of these conditions is specifically tied to different vitamin deficiencies, making scurvy the condition associated with a lack of Vitamin C.
