Vitamin A: Fat-soluble, stored in the liver.
Vitamin D: Fat-soluble, stored in body tissues and not typically excreted in urine.
Vitamin C: Water-soluble, excess is excreted in urine.
Vitamin E: Fat-soluble, stored in fat tissue, and not excreted in urine.
Step 2: Hence, the correct answer is (3) Vitamin C, which is excreted in urine when in excess.
