If we consider the set of rational numbers and the set of irrational numbers, what elements are present in both sets?

Correct option is D

Given
Two sets: the set of rational numbers and the set of irrational numbers.

Formula Used
Concept of Real Number System: A real number is exclusively either rational or irrational.

Solution
Rational numbers can be expressed in the form of $$\frac{p}{q}$$​where p and q are integers and q is non-zero. Irrational numbers are numbers that cannot be expressed in this form.
By definition, these two sets are mutually exclusive and have no elements in common.
Therefore, the intersection of the set of rational numbers and the set of irrational numbers contains no elements.
Final Answer
So the correct answer is (d)
