Answer: [D]


Irrational numbers are real numbers which cannot be represented as simple fractions.
Examples: \sqrt{2},\sqrt{3},\pi
The product of two irrational numbers can be rational or irrational depending on the two numbers.
For example, \sqrt{2}\times \sqrt{2}  is 2 which is a rational number
whereas \sqrt{2}\times \sqrt{3} is \sqrt{6} which is an irrational number.
Therefore option (D) is correct.
