Which one of the following statements is not correct?

Option 1 is not correct because milk does contain B‑vitamins — vitamin B12 is a well‑recognized micronutrient discussed in dietary sources [1]. Vitamin A deficiency (retinol/retinal forms) produces xerophthalmia and related epithelial changes including dryness of tissues, and contributes to abnormal keratinization of skin [2]. Scurvy (vitamin C deficiency) commonly presents with bleeding gums, tooth loss and joint pain due to impaired collagen synthesis and connective tissue weakening. Thiamine (vitamin B1) deficiency can produce beriberi, and the “wet” form includes high‑output cardiac failure and edema, linking B1 deficiency to heart failure presentations.
