There is no such thing as a "mineral element" - there are minerals and there are elements, but no mineral elements.
Oxygen is the most common element in ocean water, but that's not one of your choices. The next most common elements are hydrogen, than sodium, but they are still not on your list.
So the correct answer is "D" Sodium Na.

I have nothing to back this up, other than my intuition...
Sodium, b/c the oceans are salt water.... NaCl.
