Based on the law of reflection, the most accurate statement regarding the illustration is:
Light is reflecting in the direction indicated by T.
This statement confirms the fundamental principle of the law of reflection, which states that the angle of incidence (angle S) is equal to the angle of reflection (angle T). The other options do not correctly represent the law of reflection or involve concepts like refraction, which is not applicable in the context of reflection from a glossy surface like a mirror.
