Energy from the sun contributes to these two main factors that create ocean currents: and
a. wind; precipitation
b. radiation; convection
c. wind; water temperature
d. water temperature; precipitation

B

Explanation:

Ocean currents has to do with rising of cold salty water to replace the warm salty water at the top of the ocean. A convection current is thus set up continually. Convection refers to the movement of particles due to a temperature gradient between layers of fluid. Convection is one of the modes of heat transfer. Energy from the sun warm up the surface of the ocean by radiation. Hence radiation and convection are two ways by which energy from the sun affect ocean currents.

i'm assuming that the correct answer is indeed the first one/ "a"..
