As we know that the plant needs carbon dioxide, water and light. During the photosynthesis the carbon dioxide, water and sunlight react to gives glucose, oxygen and water as a product.

The balanced reaction will be,

[tex]6CO_2+12H_2O\overset{sunlight}\rightarrow C_6H_{12}O_6+6O_2+6H_2O[/tex]

Hence, the correct option is, (B) [tex]\text{carbon dioxide}+\text{water}\rightarrow \text{glucose}+\text{oxygen}+\text{water}[/tex]
