Match List I with List II

Choose the correct answer from the options given below:

A-III, B-IV, C-I, D-II

The correct answer is option 3. A-III, B-IV, C-I, D-II.

Let us look the given vitamins along with the associated diseases:

A. Vitamin C: Vitamin C, also known as ascorbic acid, is essential for collagen synthesis and acts as an antioxidant. Its deficiency leads to scurvy, which is characterized by symptoms such as weakness, fatigue, anemia, gum disease (gingivitis), skin problems (such as bruising and petechiae), and impaired wound healing.

B. Vitamin A: Vitamin A is crucial for vision, immune function, and cell growth. Its deficiency leads to night blindness, a condition where the individual has difficulty seeing in low light or darkness. Severe deficiency can lead to dry eyes, corneal ulcers, and in extreme cases, irreversible blindness.

C. Vitamin D: Vitamin D is essential for calcium absorption and bone health. Its deficiency leads to rickets in children and osteomalacia in adults. Rickets is characterized by soft, weak bones, skeletal deformities (such as bowed legs), delayed growth, and muscle weakness. Osteomalacia is a similar condition in adults where bones become soft and weak.

D. Vitamin \(B_1\) (Thiamine): Vitamin \(B_1\), also known as thiamine, is essential for energy metabolism and nerve function. Its deficiency leads to beriberi, which can manifest as symptoms such as weakness, fatigue, nerve damage (peripheral neuropathy), muscle wasting, and in severe cases, heart problems (such as congestive heart failure).

So, the correct match is:

A-III (Vitamin C deficiency causes scurvy),

B-IV (Vitamin A deficiency causes night blindness),

C-I (Vitamin D deficiency causes rickets),

D-II (Vitamin \(B_1\) deficiency causes beriberi).
