The right answer is B) carbon dioxide and water.
Photosynthesis is a biochemical process that allows green plants (chlorophyllian) to capture light energy, transform CO2 into organic carbon and restore oxygen to the atmosphere.
The balance of photosynthesis is as follows:
6 CO2 + 12 H2O + (Light energy) => C6H12O6 +6 H2O + O2.
The green plants take from the aerial parts the CO2 that will provide them with carbon and oxygen (mainly by the leaves, except for some xerophytes * such as cacti, euphorbiaceae or gaseous exchange through the stem). Hydrogen comes from the water absorbed by the plant.
From these two molecules and with light energy, the plant makes its own "food" during a process called photosynthesis.
