Answer : The correct option is, (d) [tex]O_2[/tex]
Explanation :
Cellular respiration : It is a type of process in which the glucose molecule react with the oxygen to form a great amount of energy in the form of ATP and carbon dioxide and water as a byproducts.
The balanced equation for cellular respiration will be,
[tex]C_6H_{12}O_6+6O_2\rightarrow 6CO_2+6H_2O+ATP[/tex]
Food as a glucose and oxygen are the input for the cellular respiration.
Hence, the correct option is, (d) [tex]O_2[/tex]
