Solution

The correct option is B an irrational number
A number having non-terminating and non-recurring decimal expansion is an Irrational Number.
For example, $π$ is an irrational number
and $π = 3.1415926535897932384626433832............$

Here, the number has non-terminating decimal expansion which is non-recurring.
Hence, option $C$ is correct.
