The angle at which light hits a surface (angle of incidence) and the angle at which it is reflected away (angle of reflection) are . always greater than 90 degrees.

always the same

always negative

always opposite

The same

Explanation:

θr = θi

The law of reflection states that the angle of reflection equals the angle of incidence—θr = θi. The angles are measured relative to the perpendicular to the surface at the point where the ray strikes the surface.

this allows people to make the best decision or pursue the best option. when alternatives are weighed using their advantages and disadvantages, the option whose disadvantages outweigh the advantages (based on a qualitative or quantitative analysis) are shunned while those whose advantages outweigh their disadvantages are pursued.
