Hazy weather significantly affects visibility, primarily by creating an illusion that objects are farther away than they truly are. When the atmosphere contains moisture, dust, or pollution, light is scattered, which contributes to a reduction in clarity and detail. This scattering causes distant objects to lose contrast against the background, making them difficult to discern and giving the false impression that they are at a greater distance.

As a result, pilots may not accurately judge the distance to other aircraft or terrain features, leading to potential safety issues during flight. Understanding this phenomenon is crucial for effective situational awareness, and pilots must remain vigilant in hazy conditions to ensure they can detect other aircraft or terrain at appropriate distances.

In contrast, the other choices imply either an enhancement or a neutral effect on visibility, which isn't reflective of the reality experienced in hazy conditions.
