What deficiency is most commonly associated with scurvy?

Scurvy is primarily associated with a deficiency of Vitamin C, also known as ascorbic acid. This vitamin plays an essential role in the synthesis of collagen, which is crucial for healthy connective tissues, skin, blood vessels, and bones. When there is insufficient Vitamin C in the diet, the body cannot properly form collagen, leading to symptoms such as swollen gums, joint pain, and bruising.

Individuals with scurvy may also experience fatigue, weakness, and anemia due to the role of Vitamin C in iron metabolism and absorption. This is why a deficiency in Vitamin C is directly linked to the development of scurvy, making it the correct answer. Other vitamin and mineral deficiencies, while they can lead to various health issues, do not cause scurvy.
