Hint Sun rays are very harmful to our eyes, which is why we cannot look at it directly on a normal day for extended periods of time without pinching them close. During a solar eclipse, the brightness of the light from the sun is decreased very significantly which makes it easier for us to look at it but still viewing even a small slice of the sun can be dangerous.

Complete step by step answer
On a usual day, we cannot look at the sun due to because the sun simply outputs more power than our eye is designed to handle, and exposing our eye to that kind of power can damage the retina so our eyes naturally squint and we will look away. The radiation from the sun also contains ultraviolet radiation which is also harmful to the retina.
Now when a solar eclipse occurs, the moon comes in between the Sun and the Earth, and as a result, the brightness of the sun is blocked by the moon and the brightness of the sun decreases significantly. Because of its intensity, viewing even a small slice of the sun can be dangerous. The lens of the eye focuses and concentrates the intensity of the sun rays on the retina, scorching it. The darkness that accompanies a solar eclipse can override the natural reflex to squint and look away, increasing the amount of intense light striking the retina and making eye damage more likely. Since the retina does not have pain receptors, we cannot realize the damage before it's too late and we can lose part of our vision partially or completely.
Hence the correct choice is option (A).

Note
Sun rays are not weak at all so we can discard option (B). While sun rays can cause a burn on our skin, it is not specified during the solar eclipse only so we can also rule out option (C). The intensity of light is not affected by the refraction of light so option (D) is incorrect.
