\nThe correct option is C. Statement I is true, but Statement II is false.
\n<\/section>\n
\nStatement I is true. Light entering a room, whether direct sunlight or light from outside reflected by various surfaces, undergoes diffused reflection when it strikes the walls, furniture, and other objects inside the room. Diffused reflection scatters light in multiple directions, illuminating the entire room even areas not directly hit by the initial light rays.
\nStatement II is false. Irregular reflection (diffused reflection) occurs when light strikes a rough or uneven surface. While the reflected rays scatter in various directions, *each individual ray* still obeys the laws of reflection: the angle of incidence equals the angle of reflection, and the incident ray, the normal to the surface at the point of incidence, and the reflected ray all lie in the same plane. The scattering happens because the normals to the surface at different points are oriented in different directions.
\n<\/section>\n
\nThe difference between regular (specular) reflection and irregular (diffused) reflection lies in the nature of the reflecting surface, not in the adherence to the laws of reflection. A smooth surface causes regular reflection (like a mirror), while a rough surface causes diffused reflection (like a wall).
