Answer Key

Question 1
B. Vitamin C

Scurvy is caused by a severe deficiency of vitamin C (ascorbic acid). It was common among sailors who lacked fresh fruits and vegetables during long voyages.

Question 2
D. Vitamin D

Rickets is caused by vitamin D deficiency, which impairs calcium absorption and leads to soft, weak bones. Sunlight exposure helps the body produce vitamin D.

Question 3
D. Vitamin A

Vitamin A deficiency causes night blindness because vitamin A is essential for producing rhodopsin, a pigment in the retina needed for low-light vision.

Question 4
C. Vitamin B1 (Thiamine)

Beriberi is caused by thiamine (vitamin B1) deficiency. It was historically common in regions where polished white rice was a dietary staple, as the milling process removes thiamine.

Question 5
B. Vitamin B12

Pernicious anemia is caused by vitamin B12 deficiency, often due to the body's inability to absorb B12 from food. It results in fatigue, weakness, and neurological problems.

Question 6
C. Vitamin B3 (Niacin)

Pellagra is caused by a deficiency of niacin (vitamin B3). It was epidemic in the early 20th century in areas where corn was the primary dietary staple.

Question 7
D. Vitamin K

Vitamin K is essential for synthesizing proteins needed for blood clotting. Its deficiency can lead to excessive bleeding and easy bruising.

Question 8
D. Limes

The British Navy issued lime juice rations to sailors to prevent scurvy, which is how British sailors earned the nickname 'limeys.'

Question 9
A. Neural tube defects in the baby

Folate deficiency during pregnancy significantly increases the risk of neural tube defects like spina bifida. This is why prenatal vitamins contain folic acid.

Question 10
A. Vitamin E

Vitamin E is a powerful antioxidant that protects cells from damage. Severe deficiency can cause nerve and muscle damage, vision problems, and weakened immunity.

Question 11
B. Vitamin D

Osteomalacia is the adult form of rickets, caused by vitamin D deficiency leading to impaired calcium absorption and bone softening.

Question 12
A. Animal products

Vitamin B12 is naturally found almost exclusively in animal products such as meat, fish, eggs, and dairy. Vegans may need supplements or fortified foods.

Question 13
B. Vitamin D

Vitamin D deficiency is estimated to affect about 1 billion people worldwide, partly because many people get insufficient sunlight exposure and few foods are naturally rich in it.

Question 14
C. Vitamin B2 (Riboflavin)

Riboflavin (vitamin B2) deficiency can cause cracked lips (cheilosis), sore tongue, and skin problems. Good sources include dairy, eggs, and green vegetables.

Question 15
B. Fruits and vegetables

Fruits and vegetables are the main sources of vitamin C, with citrus fruits, strawberries, bell peppers, and broccoli being particularly rich sources.
