3. A tide with the largest difference between water levels at high and low tides is known as a spring tide. Two spring tides occur in each lunar cycle. This is because a spring tide occurs when the Moon

A is closest to Earth. B and the Sun pull on Earth at a 90° angles. C and the Sun are aligned and pull on Earth. D is farthest from Earth.
