Answer:

D.) 191 degrees

Step-by-step explanation:

An exterior angle cannot be 191 degrees, because the sum of one exterior angle and one interior angle of a polygon must be 180°, and this options refers to a exterior angles that is above that restriction. So, 191° is the impossible option.

If you see the image attached, you will see that one exterior angles and one interior angle are on a straight angle which is always 180°. That's why a exterior angle cannot be more than 180°.
