Answer: [C]


Firstly, let us define a rational number.
Any number which can be represented in the form of p/q, where q is not equal to zero, is a rational number. So it is basically a fraction with non-zero denominator.
Examples: 4/5, 2/3, -6/7
So we can say that it is a type of real number.
Similarly, we can see that irrational numbers are real numbers which cannot be represented as simple fractions.
Examples: \sqrt{2},\sqrt{3},\pi
So we can say that between two rational numbers, there are infinitely many rational numbers.
For example, between rational numbers 5 and 4, there are rational numbers like... 4.1, 4.11, 4.12, 4.13....and so on.
Therefore, option (C) is correct.
