Nernst equation help

If RT/zF = 26.6 when using the Nernst equation for calculating equilibrium potential for a monovalent ion such as Na+, what would it be for Ca2+?
A. 53.2B. 13.3C. 26.6D. 39.9E. -13.3

I thought it would be 13.3 because the z is two, so you would half it. That is not an option though.

I've just noticed, B is 13.3!! But just to be sure is that right though?

I would agree with B being the correct answer let me know if it turns out to be right or wrong
