Given below are two statements: 

Assertion (A): Vitamin D can be stored in our bodies.
Reason (R): Vitamin D is a fat-soluble vitamin.
 
1. Both (A) and (R) are True and (R) is the correct explanation of (A).
2. Both (A) and (R) are False.
3. (A) is True but (R) is False.
4. (A) is False but (R) is True.
Hint: Water-soluble vitamins cannot store in the body
Vitamin D can be stored in our body because vitamin D is a fat-soluble vitamin. Water-soluble vitamins get rid of the extra vitamins during urination.
Hence, Assertion and reason both are correct statements and reason explains the assertion.
