Arranging atoms by increasing atomic size

The answer to the following question is given as choice A, I think it is a typo and should be choice B. Can someone please confirm this?

Perhaps im reading the question wrong, but isnt this quite the simple question?

If its simply atomic sizes, sodium comes before Magnesium. Sorry I cant help you out here.

Yeah it's a typo. The atomic radii for: Be=112, Mg=160, Na=186
