Solution

The correct option is A Spherical aberration
Spherical aberration is an optical effect observed in an optical device (lens, mirror, etc.) that occurs due to the increased refraction of light rays when they strike a lens or a reflection of light rays when they strike a mirror near its edge, in comparison with those that strike nearer the centre. Due to it, the image of a point object is spread in a region instead of being focussed at a point.
