Which statement describes a convex lens?
a: it is always made of glass.
b: it is thickest at the edged.
c: it absorbs most light.
d: it bends light rays inward.

A convex lens  is a type of optical lens that thicker in the center than at its edges and concentrates (converges) at a point the rays of light that pass through it.

In addition, its focal point is where parallel rays of light from the object meet, or converge. Nevertheless, it is important to note the object must be within the radius of curvature of the lens.

Therefore, a convex lens  bends light rays inward, making them converge at a point where the image is formed, and  the correct option is D.
