The word 'habit' carries a negative implication when it suggests a lack of flexibility and adaptability, as it can imply a rigid adherence to routine without consideration of changing circumstances or new information. This is best captured by option A. Option B is incorrect because it describes a positive aspect of habits, which is not the focus of the question. Option C, while true in a general sense, does not specifically address the negative implication. Option D is incorrect because it suggests a positive, universally accepted view of habits, which contradicts the question's focus on negative implications.
