Assertion : The units of all physical quantities can be expressed as combination of the base units. Reason : We need only a limited number of units for expressing all the physical quantities.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
Explanation:
According to the principles of dimensional analysis, all physical units can be expressed in terms of a combination of the base units (such as length, mass, time, etc.). By using a set of base units (e.g., length, mass, time, electric current, temperature, amount of substance, and luminous intensity) and derived units (units derived from the base units), we can express all physical quantities. So correct option is (1). The reason provides a correct explanation for why the assertion is true.

1 Newton-Meter
2 Coulomb-Volt
3 Coulomb-Farad
4 Watt-Second
Explanation:
Newton - meter \({={J}}\) Coulomb - volt \({={J}}\) Watt \({-{sec}={J}}\) and Coulomb - farad \({\neq {J}}\). So correct option is (3).
