Parsimony is where ________.

A) the model is kept as simple as possible
B) having as many variables as possible for accuracy
C) multiple models answer questions
D) none of the above

Parsimony is about choosing the simplest explanation or model that fits the data. This helps to avoid overfitting or adding unnecessary complexity, which can lead to less accurate predictions or conclusions. Therefore, the best choice is A, where the model is kept as simple as possible. B and C would go against the principle of parsimony. D is incorrect because A is a valid choice.
