Answer:
Step-by-step explanation:
The correct answer is A. Sir Francis Bacon.
Sir Francis Bacon is credited with first documenting the use of the scientific method. He was an English philosopher, statesman, and scientist who lived in the 16th and 17th centuries. Bacon emphasized the importance of observation, experimentation, and inductive reasoning in the pursuit of knowledge.
In his work called "Novum Organum," published in 1620, Bacon outlined his method for acquiring scientific knowledge. He advocated for systematic observation, experimentation, and the collection of data to form general principles and theories. Bacon's approach laid the foundation for the scientific method that is widely used by scientists today.
Although other scientists like Sir Isaac Newton and Charles Darwin made significant contributions to science, Bacon is specifically recognized for his documentation and promotion of the scientific method.
Therefore, the correct answer is A. Sir Francis Bacon.
