Hint: Acute angles are those angles whose measure will be less than ${90^ \circ }$ , and obtuse angles are those angles which will be more than ${90^ \circ }$ and less than ${180^ \circ }$ . For the straight line, the angle will be exactly ${180^ \circ }$ and for the right angle, the angle will be exactly ${90^ \circ }$ . So by using all this information, we can now answer such types of questions.

As we had seen about the right angle, which is the angle that will be exactly equal to ${90^ \circ }$ or we can say it the quarter of a full revolution.
So greater than right angle means the angle will be greater than ${90^ \circ }$ . So from the option, only one term is fulfilling this criterion and it is an obtuse angle whose measure is more than ${90^ \circ }$ and less than ${180^ \circ }$ .
Therefore, the option $\left( b \right)$ is correct.
Note: So for solving this type of question we need to go through the options and also about them. As we have seen about the obtuse angle so for a real-life example of obtuse angle, we can say that the vertical range of the visual field in humans is around ${150^ \circ }$ and another example of it will be the door, a book, a cabined, etc. wide open are some real-life examples of the obtuse angle whose measure is more than ${90^ \circ }$ and less than ${180^ \circ }$ .
