The Correct Option is A
Solution and Explanation
The respiratory quotient (RQ) is used in calculations of basal metabolic rate (BMR). It is the ratio of the volume of carbon dioxide produced by the body to the volume of oxygen consumed by the body in respiration over a period of time. It depends on the type of respiratory substrate used during respiration. RQ of fat is about $0.7 . RQ$ of carbohydrate is $1 . RQ$ of organic acids is above $1 . RQ$ of protein is $0.9 .$ RQ value gives information about the source of energy an animal is using.

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