 Fundamental quantities are those physical quantities that are independent and cannot be defined in terms of other physical quantities. These quantities are used as a basis for defining other physical quantities in terms of them. The seven fundamental quantities recognized in the International System of Units (SI) are:

  1. Length

  2. Mass

  3. Time

  4. Electric current

  5. Temperature

  6. Amount of substance

  7. Luminous intensity

Quantities that can be derived from these fundamental quantities through mathematical formulas are called derived quantities. For example, speed is a derived quantity because it is calculated as the ratio of distance (a fundamental quantity) to time (another fundamental quantity).

So, The correct answer is Option 2.
