Answer
Correct option: D.
a real number.
A number whose square is non-negative, is called a real number.
The numbers of the form $\frac{\text{p}}{\text{q}},$ where $p$ and $q$ are integers and $\text{q}\neq0,$ are known as rational numbers.
So, a rational number is a real number since $p$ and $q$ which form a rational number are integers.
Hence, the correct opion is $(d).$
