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.
