The correct answer is: B.Light from the sun, water from the soil, and carbon dioxide from the air.

For photosynthesis to occur, a plant needs three key things:

1.Light from the sun – provides the energy needed for the photosynthesis process.

2.Water from the soil – absorbed by the roots, water is split during photosynthesis to provide electrons and protons (hydrogen ions).

3.Carbon dioxide from the air – taken in through the stomata (small pores in the leaves), carbon dioxide is used to produce glucose during photosynthesis.

Photosynthesis is the process by which plants convert light energy into chemical energy in the form of glucose, with oxygen as a byproduct. The general equation for photosynthesis is:
