A body function that may be affected by a deficiency of vitamin C is:

A. synthesis of intrinsic factor: Vitamin C does not play a role in the production of intrinsic factor, which is a protein needed for vitamin B12 absorption. Deficiency of vitamin C would not impair this process. B. Wound healing: Vitamin C is essential for collagen synthesis, which is crucial for tissue repair and wound healing. A deficiency can result in delayed healing, easy bruising, and poor connective tissue integrity. Monitoring for slow recovery from injuries can indicate inadequate vitamin C intake. C. bowel elimination: Vitamin C does not directly regulate bowel movements, although high doses may have a mild laxative effect. Deficiency does not typically cause significant changes in bowel elimination. D. urine formation: Vitamin C is water-soluble and excreted in urine, but it does not affect kidney function or the process of urine formation. Deficiency does not impair renal filtration or fluid balance.
