Solution

The correct option is D $5 + \sqrt{9}$
We know that, $\sqrt{2}, \sqrt{3}$ are irrational numbers.
So, if we add any number to $\sqrt{2}, or \sqrt{3}$ , the resulting number will also be irrartional.

Also, $\sqrt{9} = 3$ is not an irrational number.
Hence, $5 + \sqrt{9} = 5 + 3 = 8$ is not irrational.
