Answer:
The correct answer will be option-A
Explanation:
The respiratory system is the series of organs which is links the internal gases with atmospheric gases that is it is responsible for the exchange of gases in the animal kingdom.
The respiratory system involves the intake of oxygen and exhalation of carbon dioxide as a waste product.
The primary organs involved in the respiratory system are the lungs which along with the circulatory system transports the oxygen to every cell of the body.
Since the respiratory system along with the circulatory system allows the transport of oxygen to every cell therefore, option-A is the correct answer.

The correct answer is: B) "All roads lead to Rome"
Citric acid cycle also called tricarboxylic acid (TCA) cycle and Krebs cycle is a central process in cellular respiration. Citric acid cycle that connects carbohydrate, fat, and protein metabolism so “all the roads” from the different metabolic pathways come to this cycle.
Acetyl-CoA which is produced through the oxidation of pyruvate (pyruvate is a product of glycolysis) enters the cycle which then produces reduced electron carriers NADH, FAD2 and energy molecule ATP. These electron carriers will then pass their electrons into the electron transport chain and, through the process of oxidative phosphorylation, will produce more ATP.
