The correct answer is B. low tide.
A low tide is the lowest level of the sea during a tidal cycle. It occurs when the gravitational pull of the Moon and the Sun are at their weakest. Low tides are usually about six hours apart, and they can vary in height depending on the location.
A spring tide is a tide with a higher than average range. It occurs when the Moon is either full or new, and the Sun, Moon, and Earth are aligned. Spring tides are the highest tides of the month.
An ebb tide is a tide that is receding. It occurs when the gravitational pull of the Moon and the Sun are pulling the water away from the shore. Ebb tides are usually about six hours apart, and they can vary in speed depending on the location.
None of the above is not the correct answer.
