The favorable weather elements for dew include clear skies, light wind, decent soil moisture. Clear skies allow for the maximum release of longwave radiation to space.
Cloudy skies will reflect and absorb while remitting longwave radiation back to the surface and that prevents as much cooling from occurring. So B is the most appropriate reason.

Explanation:
Clouds reflect back the Earths radiation.
When the Earth's surface cools down at night, the air close to the surface also cools down. If the temperature of the air drops below the dew point temperature, the moisture in the air condenses and forms dew. Dewdrops are formed on surfaces that are cooler than the surrounding air, such as blades of grass or the roof of a car.
Clouds act like a blanket, trapping the radiation that is released by the Earth's surface at night. This radiation warms up the air near the surface, preventing it from cooling down enough to reach the dew point temperature. Clouds also reflect back the radiation that is released by the Earth's surface, which contributes to the warming effect.
On a cloudy night, the radiation that is released by the Earth's surface is absorbed or reflected by the clouds, preventing it from reaching the air close to the surface. This means that the air close to the surface does not warm up as much as it would on a clear night, and does not reach the dew point temperature. Therefore, dewdrops are not formed on a cloudy night.
In summary, the formation of dewdrops requires the air close to the surface to reach the dew point temperature, which is prevented on a cloudy night because clouds reflect back the radiation that is released by the Earth's surface.
