Answer:
A - False
B - False
C - True
D - False
Explanation:
A - Radiation mainly occurs in vacuum, it doesn't mean it doesn't occur through air, but in a very negligible and minute content which can be said as almost no.
B - Land breeze occurs due to Convection. The land cools faster than water bodies. So the hot air above the water bodies rises up and hence the cold air with pressure rushes towards the water body.
C - Cold air is heavier than warm air as it is dense.
D - Water is not a good conductor of heat as it cannot conduct heat and it takes part in convection but not in conduction.
