I don't think D is the right answer. Post your work.

The answer is in fact, D. No work has to be done here, just several inputs into the calculator should suffice. To begin, you already have moles, so that makes things much easier. Now from moles, you go to atoms with the conversion of (6.022e23 atoms/ 1 mole) and you'll get 7.56e24, and so the answer to this problem is D.
