The Correct Option is D

Solution and Explanation

Deep breathing rises the $O _{2}$ level of the blood. Acidity of blood increases due to excess formation of oxyhaemoglobin.

Respiration in Plants

Respiration in plants is a process that entails the production of energy in plants. This process can simply be described as the intake of Oxygen and the release of Carbon Dioxide as an outcome of the oxidation of complex organic compounds. Though plants do not have any specific organ to balance the process of respiration, their stems, roots, and leaves do this work at a very low rate than other living beings. The process of respiration is very crucial for the plants to sustain the growth of the plant tissues.

This process can be stated as-

\[C_6H_{12}O_6 + 6O_2 → 6CO_2 + 6H_2O + \text{Energy}\]
