Show answer & explanation
Correct answer: B
Fog consists of fine water droplets that scatter visible light, which reduces the visibility of distant objects. Even though individual water molecules are transparent to light, the droplets in fog scatter light in all directions due to their size and density. This scattering prevents light from traveling straight through the fog, making distant objects appear blurry or invisible.
