Final answer:
An empirical method of acquiring knowledge is based on observation and experimentation, key aspects of the scientific method. Therefore, the correct answer is 'C. scientific'.
Step-by-step explanation:
An empirical method of acquiring knowledge refers to a process that relies on observation and experimentation to understand the natural world. This stands in contrast to rationalism, which is based on reason and deduction.
The empirical approach is a cornerstone of the scientific method, which includes careful observation, formulation of hypotheses, experimentation, and modification of hypotheses based on empirical evidence.
Empiricism is grounded in the belief that knowledge comes through our senses. It emphasizes evidence and experimentation, and in the context of the scientific method, it requires that hypotheses and theories be tested against observations of the natural world.
Notable empiricists such as Bacon, Locke, Berkeley, Hume, and Mill have influenced this approach significantly.
Therefore, in the given group of answer choices, the most appropriate option that describes an empirical method of acquiring knowledge is C. scientific.
