Answer
- a real number.
Solution:
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).
