Deficiency of which vitamin or mineral results in an inadequate inflammatory response?
- A. A
- B. B1
- C. C
- D. Zinc
Correct Answer: A
Rationale: A deficiency of vitamin A results in an inadequate inflammatory response. Vitamin A is essential for maintaining immune function and epithelial integrity, which are critical for an effective inflammatory response. Deficiencies of vitamins B1 and C impair collagen formation, necessary for wound healing, while a zinc deficiency leads to impaired epithelialization, affecting tissue repair rather than the inflammatory response.
