Explanation

Soft drinks, especially colas, contain caffeine as a key ingredient to provide a mild stimulating effect and a specific flavor profile. Manufacturers add caffeine to these beverages to enhance their addictive quality and taste. Nicotine is a stimulant found primarily in tobacco products, not in soft drinks. Tannin is a bitter compound found in tea, coffee, and wine. Renin is an enzyme produced by the kidneys in humans that helps regulate blood pressure. Therefore, caffeine is the only substance among the choices present in significant quantities in colas.
