Final answer:
Option 3). Scurvy is associated with a deficiency of ascorbic acid, also known as vitamin C, which is abundant in citrus fruits.
Step-by-step explanation:
Ascorbic acid, or vitamin C for short, is the acid linked to scurvy. High concentrations of ascorbic acid are found in citrus fruits, such as lemons and oranges. A vitamin C shortage causes scurvy, a disorder that manifests as bleeding gums, hair loss, tooth loss, joint discomfort and swelling, and slowed wound healing. James Lind's discovery in the eighteenth century that citrus fruits may ward off scurvy served as a historical marker for the importance of vitamin C and improved the health of sailors on extended voyages.
