What nutrient deficiency can lead to scurvy?

Scurvy is specifically caused by a deficiency in vitamin C, also known as ascorbic acid. This vitamin plays a crucial role in the synthesis of collagen, which is important for the health of connective tissues, skin, blood vessels, and bones. Without sufficient vitamin C, the body cannot effectively produce collagen, leading to symptoms such as fatigue, joint pain, and the hallmark signs of scurvy, which include swollen gums, bruising, and poor wound healing.

Vitamin C is also vital for the absorption of iron from plant-based sources and helps in the overall immune function. Because other choices pinpoint different vitamins and a mineral that do not directly relate to the symptoms or the biology underpinning scurvy, they do not cause this specific disease. Thus, the identification of vitamin C deficiency as the cause of scurvy is essential for understanding the importance of this nutrient and its role in maintaining health.
