Question

What factor will most likely determine where a wave current project can be located?

Answer 1

Well, it doesnt matter about the temperature of the water, so B is out. The weather doesn't really tell us where a wave current can form, so A is out. Its would be between B and D now. With D, no matter the type of wave, currents can still form. I would pick B. 

Answer 2

Answer;

Presence of waves

Explanation;

The factor that is most likely to determine where a wave current project can be located is the presence of waves.

The presence of a wave that is being targeted to be used in a wave project is key in determining the location of the project, because without the wave then the project would not exist in the first place.
