The correct answer is option 3, Vitamin C. Scurvy is a condition caused by a deficiency of Vitamin C in the body. Vitamin C is an important nutrient that plays a key role in the production of collagen, a protein that helps form connective tissues, blood vessels, and skin. When the body lacks Vitamin C, the production of collagen is disrupted, leading to symptoms of scurvy. These symptoms include fatigue, weakness, swollen and bleeding gums, slow wound healing, and joint pain. It is important to note that options 1, 2, and 4 are incorrect. Vitamin A deficiency can cause night blindness and other vision problems, Vitamin B deficiencies can lead to various health issues including anemia, and Vitamin D deficiency can cause problems with bone health.
