Final answer:
B) Less
The correct answer to 'The higher the % cacao, the _______ sweeteners used.' is 'less'. A higher % cacao indicates a higher amount of chocolate originating from cacao beans and correspondingly less room for sweeteners like sugar.
Step-by-step explanation:
The higher the % cacao, the less sweeteners used. The correct answer is B) Less. Chocolate is made from cacao beans, and the percentage of cacao in a chocolate product indicates the amount of chocolate originating directly from these beans. In chocolate production, cacao and sugar are two of the primary ingredients. A higher percentage of cacao means that more of the product is made up of cacao, leaving less room for sugar and other sweeteners. For example, a 70% cacao chocolate bar consists of 70% cacao products (such as cacao solids and cacao butter) and 30% other ingredients, which often mainly consist of sugar. Therefore, as the percentage of cacao increases, the proportion of sweeteners decreases.
