The correct answer is option 3: 12 hours. This means that the interval between two high tides is approximately 12 hours.

Now, let`s go through each option to understand why the correct answer is option 3 and not the others.

Option 1: 4 hours. It is unlikely for the interval between high tides to be only 4 hours. Tides are influenced by various factors such as the gravitational pull of the moon and the rotation of the Earth, which typically result in longer intervals between high tides.

Option 2: 6 hours. While this is a commonly known interval for the duration of a tidal cycle, it refers to the time it takes for a complete cycle of high and low tides, not just the interval between two high tides.

Option 3: 12 hours. This is the correct answer. The interval between two high tides is approximately 12 hours. This is due to the gravitational pull of the moon causing a bulge in the ocean, creating a high tide, which occurs twice a day.

Option 4: 24 hours. This interval refers to a complete cycle of high and low tides. It takes approximately 24 hours for two high tides to occur, but the specific
