Scurvy is caused by not having enough ________, resulting in general weakness, anaemia, gum disease and skin bleeding.

ascorbic acid

The correct answer is Option (2) – ascorbic acid

Scurvy is caused by a deficiency of ascorbic acid, commonly known as vitamin C. Ascorbic acid is an essential nutrient required by the body for various functions, including the synthesis of collagen, a protein found in connective tissues such as skin, blood vessels, and bones.

When there is a lack of vitamin C in the diet, the body is unable to produce collagen effectively. This deficiency leads to weakened blood vessels, impaired wound healing, and breakdown of connective tissues, resulting in symptoms such as general weakness, anemia, gum disease, and skin bleeding.

To prevent scurvy, it's essential to consume an adequate amount of vitamin C-rich foods, such as citrus fruits, strawberries, kiwi, bell peppers, and broccoli, or to take vitamin C supplements if dietary intake is insufficient.
