      [C] They convert carbon dioxide and water into carbohydrates in the absence of sunlight
      Plants are called Autotrophs. As they obtain the required energy & carbon from carbon dioxide (CO₂ gas) and sunlight. As sunlight is necessary for all living beings. They make carbohydrates from CO₂ gas & H₂O. Hence, you should go with the option [C].
