Concept:

• Nutrition is a process by which an organism consumes and uses food materials.
• According to WHO, Nutrition is the intake of food, considered in relation to the body's dietary needs.
• There are various modes of nutrition mainly Autotrophic, Heterotrophic, Chemoautotrophic, Saprophytic,  etc.

Explanation:

• Holophytic or autotrophic nutrition: In this type of nutrition the organisms prepare their food by themselves. Eg - green plants.
• Plants prepare their food by the process called photosynthesis. 
• During photosynthesis, plants trap solar energy or light energy with the help of chloroplast present in the green leaves and convert it into Chemical energy
• A pigment called chlorophyll is present in the chloroplasts which are required in trapping sunlight
• Plants utilize Carbon dioxide and Water for the synthesis of carbohydrates during photosynthesis, oxygen is liberated as a side product
• This gaseous exchange occurs through the stomata present on the leaf surface

• These events can be demonstrated by the following equation:

  \(\rm \underset{(Carbon\ dioxide)}{6CO_2} + \underset{(Water)}{6H_2 O} \xrightarrow[Chlorophyll]{Sunlight} \underset{(Carbohydrates)}{C_6H_{12}O_6} + \underset{(Oxygen)}{6O_2}\)

Therefore, Plants require CO₂, Chlorophyll, Sunlight and water for autotrophic nutrition and hence the correct option will be ''All of these''.
