Physioex 9 Ex 3 Act 3 Post Lab Action Potential HELP PLS!

Well I am going to try and answer - I may be wrong - and if so I hope someone corrects us !
K+ on the outside of the cell wall (extracellular) would mean the charge is more negative inside the cell relative to the increased positive k+ ions outside so D) ? Also since sodium (Na+?) is a positive charge it makes sense the cell would try and keep positive charge inside the cell to maintain charge equilibrium so it would decrease the flow of Sodium out fo the cell so also A) ? I am only looking at it from a charge perspective - like to get some feedback too to see if this is right.
