If we are talking about one single carbon atom, then 4 hydrogen atoms can be bonded to a carbon atom, because there is 4 electrons in the valence shell, and a valence shell needs 8 electrons in total, which causes the carbon to have 4 open bonds. A hydrogen has only one electron in its valence shell of 2, and needs one more to complete it. So, each hydrogen connects to 1 of 4 bonds on the carbon to complete the valence electron.
Fun fact, CH4 is methane.

The correct answer is - B) ATP and NADPH.
The products of the light reactions of the process of photosynthesis are the ATP and NADPH. The small amount of ATP produced in this process and the energy carrier NADHP are crucial for the functioning of the organisms that use the process of photosynthesis, and the reason for that is that these two are used by the organisms to create glucose, or rather sugars, in the process called the Calvin Cycle. The glucose is what these organisms use as their food, a food they they manage to make themselves, thus making them producers. If the light is missing, then the process of photosynthesis can not be performed because the formation of ATP's will be stopped, as well as the formation of NADHP, so the organisms will not be able to produce their own food.
