Final answer:
The final reflected ray will maintain the same angle as the initially incident ray due to the law of reflection, assuming all mirrors are perfectly aligned. Without additional information, we can't determine a specific angle from the provided choices.
Step-by-step explanation:
The question involves the concept of Light Reflection, specifically related to mirrors. This falls within the realm of Physics, part of the subject of Optics.
It's important to keep in mind that the law of reflection states that the angle of incidence equals the angle of reflection. Therefore, the final angle will be the same as the initially incident angle. Let's denote the initial angle of incidence as IA. Since the ray is incident at point A on mirror M1 and is reflected, it will maintain the same trajectory and keep the same angle after being bounced off of Mirrors M2 and M3, given that these mirrors are all perfectly aligned. The final ray (CR) will therefore maintain the same angle IA as when it first struck M1.
Without additional specifics about the initial angle or the orientation of the mirrors, we can't define a specific angle from the provided choices. However, the essential concept to understand here is that the angle of reflection equals the angle of incidence as per the law of reflection.
