Answer :
Final answer:
Starbucks Grande Coffee (16 oz.) contains the greatest amount of caffeine, significantly more than the other beverages listed, like hot chocolate, Coca-Cola Classic, or a teaspoon of Folgers instant coffee. So, the correct answer is option b) 16fl oz of Starbucks brewed coffee.
Explanation:
Looking at the beverages listed, Starbucks Grande Coffee (16 oz.) contains the greatest amount of caffeine. An 8 oz. serving of plain brewed coffee typically contains between 102 to 200 mg of caffeine. When we double that volume to match a 16 oz. serving similar to the Starbucks Grande Coffee, we find that amount could range from 204 to 400 mg. According to the data presented, a Starbucks Grande Coffee (16 oz.) specifically contains around 380 mg of caffeine, which is within this range and much higher than the typical caffeine content found in hot chocolate, Coca-Cola Classic, or a teaspoon of instant coffee, making it the beverage with the highest caffeine content amongst the options given.
For reference, hot chocolate and sodas like Coca-Cola Classic typically have much lower caffeine levels. Coca-Cola Classic (12 oz.) contains a significantly lesser amount than Starbucks Grande Coffee, and hot chocolate would contain even less than Coca-Cola Classic. A rounded teaspoon of Folgers instant coffee might come close depending on how strong it is made, but it is still unlikely to surpass the caffeine content of the Starbucks Grande Coffee (16 oz.).
