Which statement is true about the product of a nonzero rational number and irrational number

The product will be some (other) irrational number.

If the rational number is 1, then 1 times the irrational number is itself. Nothing changes.

If the rational number is not 1 (and also nonzero), and you multiply it with some irrational number, then the result will be some other irrational number.

Rule:

x*y = z

x is rational, y is irrational, z is irrational
