Answer

  1. 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).
