The angle shown in the given figure is: 

Given:

The figure 

We have to identify that the angle is of $90°$ or more than it or less than it.

A angle of $90°$ looks like this.

Now, if the standing line it bent towards right, it is an angle more than $90°$and if the standing line it bent towards left, it is an angle less than $90°$.

Hence, option B is correct.
