Answer:
The correct answer is C: A spring tide can occur for both position A and position B.
Explanation:
The explanation for the above is very straightforward.
When the moon is between the sun and the earth and when the earth is between the sun and the moon, the gravitational forces of both the sun and the moon tend to exert a pull the earth whose surface is 70% water thus creating higher tides.
These types of tides are called spring tides and occur when the moon is full and when there is a new moon.
Full moon occurs when the earth is inbetween moon and the sun while the new moon occurs when moon is between the sun and the earth.
Cheers
