Final answer:
The statement identifies 'Observation and Questioning' as the first step of the scientific method, which involves asking a question based on initial observations (Option A).
Step-by-step explanation:
The statement 'Does the amount of sugar a person eats affect their energy level?' illustrates the Observation and Questioning step of the scientific method. This is the very first step in the process, where an observation leads to a curiosity or question that the scientist wants to explore further.
The subsequent steps would involve doing background research, forming a hypothesis, testing the hypothesis through experiments, analyzing the data, and finally drawing conclusions.
Thus, the correct option is A.
