Which is correct — OS’s, OSes or OSs?

Writing for Business

typing Which is correct?
The criteria for choosing among ____ for mobile devices are complicated.
a. OS’s
b. OSes
c. OSs

Answer: c.
The rule for pluralizing abbreviations is to simply add an “s,” and according to most sources, that holds true for those that end in “s.” Others recommend adding an apostrophe to make the initialism or acronym less confusing. But maybe the least confusing thing to do is have a rule and stick to it.
