Your answer: C was correct!
Our quote is in terms of the number of dollars per euro, and a direct quote for euros is the number of euros per dollar. So, we must invert the rates given to get USD:EUR = 0.8256/0.8263. The spread is the difference between the bid and the ask or 0.8263 ? 0.8256 = 0.0007. The spread as a percent of the ask price is (0.0007 / 0.8263) or 0.0847%. Rounding is per market convention.
