Answer is D as both precipitation and condensation are involved in formation of dew in humid nights. The water vapor condenses to form clouds. But, if precipitation was not there, the dew would have remained in the clouds! So, precipitation is also involved in formation of dew on humid nights. Q and R are condensation and precipitation respectively. Thus, the answer is D(condensation and precipitation) and not B(only condensation).
