What distinguishes Arabica beans from Robusta beans?

Arabica beans are known for their distinct flavor profile, which is characterized by a balance of sweetness and acidity. This delicate flavor complexity makes Arabica beans highly sought after in specialty coffee markets. They tend to have a smoother taste, often with hints of fruit and a pleasant brightness.

On the other hand, Robusta beans are recognized for their stronger, more bitter flavor and a higher caffeine content, which contributes to their bold characteristics. While they may be favored in some espresso blends for their crema and body, Arabica's unique sweetness and nuanced acidity are what set it apart. This makes option B the most accurate choice, as it encapsulates the fundamental differences between the two types of beans without overgeneralizing their attributes.

In terms of the other options, they incorrectly represent key characteristics of both bean types, making them less accurate compared to the chosen answer.
