Solution Verified by Toppr

Correct option is A)

Let x be a rational number and y be an irrational number.

Let xy=a.

Let us assume that a is rational.

Since, a is rational it can be expressed as

q p ​

, where p and q are integers.

Let x= n m ​

, where m and n are integers.

Now, xy=a n my ​ = q p ​ .

On cross multipliying we get,

⇒y= qm pn ​ .

Now, pn and qm are integers.

Hence, qm pn ​

is a rational number.

However, y is irrational.

Hence, our assumption is incorrect.

Hence, the product of a non-zero rational and an irrational number is always an Irrational number.

So, option A.
