Detailed Solution

According to the law of reflection of light,
Angle of incidence = Angle of Reflection,
where, the angle of incidence is the angle between the incident ray and the normal, and the angle of reflection is the angle between the reflected ray and the normal.

The angle of incidence = 35^o
Therefore, the angle of reflection will also be 35^o. Therefore, the angle between the incident ray and the reflected ray will be 35^o + 35^o = 70^o.

Hence 70^o is the correct answer.
