Due to attraction of the sun and the moon, what is the frequency of up and falls down of ocean water in a day?

Correct option is A

(a) Two
The gravitational forces exerted by the moon, and to a lesser extent the sun, cause the tides. Most coastal areas on Earth typically experience two high tides and two low tides each day.
High Tide: When the water level is at its highest point.
Low Tide: When the water level is at its lowest point.
Spring Tides: Occur during the full moon and new moon phases.
The gravitational forces of the Moon and the Sun work together, resulting in higher high tides and lower low tides.
Neap Tides: Occur during the first and third quarters of the moon.
The gravitational forces of the Moon and the Sun are perpendicular to each other, resulting in less extreme tides.
