Answer and Explanation :-

Answer: Option 4

Explanation:

Physical quantities which are independent of each other and cannot be further resolved into any other physical quantity are known as fundamental quantities.Electric Current, temperature and luminous intensity all of these units individually combine and form some other units in physics. So none of these is a derived quantity.
