Answer 2

0 is the correct option.

Step-by-step explanation:

We have been given the number π, which is an irrational number. The value of π is 3.14

Now, let us multiply the number π with the given numbers in option and see what type of number we get.

`0* \pi = 0\\\\1\pi * \pi = \pi^2\\\\-\pi * \pi = -\pi^2\\\\2* \pi = 2\pi`

Among all the above result, only 0 is a ration number.

Hence, when we multiply 0 with π then the result will be a rational number.
