Option 1: Lens with power +2.0 D

A lens with a positive power (+2.0 D) will converge the light rays, causing them to come together at a focal point. This will bend the light rays, but the angle of bending will be less compared to a lens with a higher power.

Option 2: Lens with power +2.5 D

A lens with a higher positive power (+2.5 D) will bend the light rays through a larger angle compared to the previous option. This is because the lens has a stronger converging effect and will bring the light rays to a focus at a shorter distance.

Option 3: Lens with power -1.5 D

A lens with a negative power (-1.5 D) will diverge the light rays, causing them to spread out. This will also bend the light rays, but in the opposite direction compared to a converging lens. However, the angle of bending will be smaller compared to a lens with a positive power.

Option 4: Lens with power -2.0 D

Similar to option 3, a lens with a negative power (-2.0 D) will also diverge the light rays. The angle of bending will be larger compared to option
