I know this is the correct answer because i just took this quiz and got a 100%. Hope I helped! :)

Answer: The correct option is A.

Explanation: Plants produce their food by the process of photosynthesis.

Photosynthesis is a process in which plants use energy from sun, carbon dioxide from air and water to produce glucose and oxygen.

Equation for photosynthesis is given by:

\(Sunlight+6CO_2+6H_2O\rightarrow C_6H_{12}O_6+6O_2\)

Plants obtain carbon in the form of carbon dioxide from the air.

Thus, the correct option for this question is A.
