Alan is most likely to find:

**A. The difference between high and low tide is greatest during full moons and new moons.**

This is because tides are influenced by the gravitational pull of the moon and the sun. During full moons and new moons, the Earth, moon, and sun are aligned, leading to higher high tides and lower low tides, which results in a greater difference between the two (known as "spring tides"). Conversely, during the first and last quarters of the lunar cycle, the moon is at a right angle relative to the Earth and the sun, leading to lower high tides and higher low tides (known as "neap tides"), which results in a smaller difference.
