• B. irrational number
• C. co-prime number

Answer 1

The correct option is B irrational number

An irrational number cannot be represented in the form of $\frac{p}{q}$ where $p$ and $q$ are integers and $q\ne 0$. A non-terminating and non-recurring decimal cannot be represented in the form of $\frac{p}{q}$ where $p$ and $q$ are integers and $q\ne 0$. Hence, it is an irrational number.
