A
Farrel’s Law
B
Ocean currents
C
Attraction of the moon
D
Pressure system of the earth
Explanation: 

Detailed explanation-1: -Gravity is one major force that creates tides. In 1687, Sir Isaac Newton explained that ocean tides result from the gravitational attraction of the sun and moon on the oceans of the earth (Sumich, J.L., 1996).

Detailed explanation-2: -Tides are very long waves that move across the oceans. They are caused by the gravitational forces exerted on the earth by the moon, and to a lesser extent, the sun.

Detailed explanation-3: -Even though the sun is much more massive and therefore has stronger overall gravity than the moon, the moon is closer to the earth so that its gravitational gradient is stronger than that of the sun.
