Answer:
.C. Refraction of light passing through the lens.
Explanation:
The convergence or divergence of the rays of light is only due to refraction of light. When a ray of light is made to pass through a lens, it bend's from it's original path. This bending of light from its original path is called Refraction. Whereas in Reflection the ray of light is reflected back into the same medium.
Hence the correct option is C. Refraction of light passing through the lens.
