Detailed Solution

The assertion is incorrect, but the reason is correct.
Assertion: For a plane mirror, the angle of incidence is 0 degrees, NOT 90 degrees, if the incident ray falls along the normal. The mirror's normal is used to measure the angle rather than the mirror's plane. As a result, the angle of reflection is 0 degrees.
Reason: Additionally, all typical reflections adhere to the reflection laws. As a result, both the reason and the assertion are true.
