Concept:Theorems are proved using logical reasoning based on established axioms and rules, not by experiments or simple observation.
Explanation:Mathematical proofs rely on deductive reasoning.
Deduction starts from known premises or axioms.
By applying logical steps, we derive new conclusions.
This process shows a theorem must be true.
Experimentation, verification, and observation only suggest patterns, but do not give absolute proof in mathematics.
Answer:B. Deduction
