E
membrane excitability increases when Extracellular K+ decreases, decrease H+ may associate with decrease K+, I guess so.

Guys, I think all of us were right, but the question was "by the greatest amount". B, D and maybe even E could be, but it seems that D is "by the greatest amount"

why not a?Increasing extracellullar Na+ will cause more Na to flow in causing excitability??

may be D is the correct answer. due to easier depolarization caused by decreased calcium as in tetany due to hypocalcemia

I think this is the case - words "by the greatest amount"
