Which principle is commonly phrased as 'Occam's Razor'?

• A. Law of Complexity
• B. Law of Generalization
• C. Law of Reinforcement
• D. Law of Parsimony

Answer: (D)

Occam's Razor is a principle that favors the simplest explanation that makes the fewest assumptions. This idea is commonly called the Law of Parsimony because it emphasizes keeping explanations lean and not multiplying entities beyond necessity. In practice, it helps us avoid overcomplicating our interpretations of behavior or phenomena when a straightforward account fits the data. The other ideas describe different concepts: a “Law of Complexity” would push toward more complex explanations, “Law of Generalization” concerns applying findings broadly, and “Law of Reinforcement” relates to learning from consequences. So the wording associated with Occam's Razor is the Law of Parsimony.
