Answer 2

Option A.

Explanation:

A rational number is a number that can be expressed in a fraction (ratio of integers).

Option A is rational since both quantity are rational

Option B is irrational since

`√(3)\cdot√(9)=√(27)`

where 27 is not a square of any fractions/ integers. Hence, it cannot be expressed as a fraction and is irrational.

Option C is irrational. Note that PI is irrational. Any rational multiples of an irrational number must also be irrational.

Option D is irrational. Similar to Option B.
