I think that the question is not clear enough. Can you be more specific?
If your question was something like this: how many atoms of hydrogen can be around carbon, then the answer is 4. Carbon forms 4 bonds with other atoms.
Please note that carbon need not always form bonds to four atoms. A carbon could form a double bond with an oxygen and then two single bonds to hydrogen atoms. The carbon is only bonded to three atoms, but is forming a total of four bonds (1 double and 2 singles).

Answer:
D.Convention
Explanation:
The four main mechanisms that lift the air in the atmosphere and create clouds are a) Convection; b) Convergence; c) Updraft and d) Orographic Lifting
Radiation, conduction and water vapor are not responsible for creating lift in the atmosphere.
In convection, heat energy from sun raises the temperature of surface of the earth as it passes through the atmosphere. The air near the surface become less dense and hence starts rising thereby creating a lift.
