Explanation:

- The gravitational pull of the moon and the sun causes ocean water to rise and fall, creating tides.

- Tides typically result in two high and two low tides each day.

- This cycle creates approximately a 12-hour period between each high and low tide.

- The lunar cycle primarily influences tidal patterns, with the sun having a secondary effect.

- Option 1: Two – This is the correct choice, as there are two high tides and two low tides daily, totaling four tidal events.

- Option 2: Three – Incorrect, because tides happen twice daily, split into four events.

- Option 3: Four – Misleading, as it implies a complete cycle beyond two high and two low tides.

- Option 4: One – Incorrect, as it implies only one tidal change per day.
