Which of the following is a characteristic of a good theory or explanation?

AIt is parsimonious

BIt is testable

CIt is general enough to apply to different situations

DAll of the above ✓ Correct

Correct answer: (D) All of the above

Explanation

A good theory is parsimonious, testable and general, so every listed trait qualifies.

Parsimony means it explains the most with the fewest assumptions.

Testability lets it be confirmed or refuted through evidence.

Generality lets it apply across many different situations.

Naming only one trait would leave out equally essential features.

Good theories are also internally consistent and empirically fruitful.
