Answer:
The answer is letter a, Deductive Reasoning.
Explanation:
Reasoning- this is the act of thinking about something in a logical and sensible way. There are many types of reasoning but we'll focus on <em>deductive reasoning. </em>
Premise- a statement in an argument that provides reason or support for the conclusion.
Conclusion- a judgment or decision reached by reasoning.
Deductive Reasoning- this is also known as <em>"deductive logic." </em>This is the process of reasoning from one or more statements in order to reach a conclusion. It moves from generalized principles that are known to be true to a true and specific conclusion.
In the example above, the generalized principle is "All prokaryotes lack a well-defined nucleus." The premise is "The newly discovered cell has no well-defined nucleus." The conclusion is " Therefore, the newly discovered cell is a prokaryote."
Thus, the example above follows the deductive reasoning pattern.
