Hey, I think the answer is B) because the compound is the same on both sides.. So it would only have one peak.. All of the Hydrogens are equal, which makes them only have one peak, there is equal splitting from neighboring Hydrogens cause they are all attached to the same thing.. hope that helps..

I think it's B as well due to the symmetry of the molecule. So only 1HNMR peak.

thanks thanks. i understand it now

I agree with the above posters. The answer is B. 1H NMR peaks are for unique hydrogens. Since all of the hydrogens in answer B are in similar environments, there will will only be 1 peak.
