Answer 1

The correct option is A True

• Oxygen $\left({\mathrm{O}}_2\right)$ is the second most abundant gas in the atmosphere.
• It is a chemically reactive gas.
• Oxygen is required for obtaining energy from the food we eat. This process is called respiration.

$\mathrm{Food}+\mathrm{Oxygen}\to \mathrm{Carbon}\mathrm{dioxide}+\mathrm{Water}+\mathrm{Energy}$

Hence, the given statement is true.
