Explanation:
Vitamin A (retinol) is crucial for the synthesis of rhodopsin, maintaining normal vision, especially in dim light. Vitamin D deficiency impairs calcium absorption, leading to rickets in children. Vitamin C (ascorbic acid) is a water-soluble vitamin, not fat-soluble; vitamins A, D, E, and K are fat-soluble. Thus, statements 1 and 3 are correct.

Explanation:
Vitamins A, D, E, and K are fat-soluble, stored in body fats and liver. Vitamin K is essential for blood clotting (synthesis of prothrombin). Vitamin B complex and vitamin C are water-soluble, excreted in urine and not stored extensively. Fat-soluble vitamins require dietary fat for absorption. Excess of fat-soluble vitamins can cause toxicity (hypervitaminosis).
