AI Explanation
The correct answer is D) when the moon is new or full. Spring tides occur when the gravitational pull of the sun and moon are aligned, either on the same side of the Earth (new moon) or on opposite sides of the Earth (full moon). This increased gravitational pull results in higher high tides and lower low tides, known as spring tides. The other answer choices are incorrect because they do not accurately describe the conditions that lead to spring tides.
