A Correct answer
Explanation

The time between two high tides averages 12 hours and 25 minutes, not exactly 12 hours. This is because the Moon takes approximately 24 hours and 50 minutes (not 24 hours) to return to the same position relative to Earth's surface, so the tidal cycle is half of that period. Option B would be the time between high and low tide, not between two high tides.
