The skateboards that belong to the guys which shows how to correctly rewrite this phrase using an apostrophe?
a. the guys' skateboards
b. the guys's skateboards
c. the guy's skateboards
d. the guys skateboards'

a. the guys' skateboards.

Option A is the one that correctly uses the possessive form. Most of the time, when we are turning a noun into a possessive, we add an "s" if the noun is singular:

Ex. the bike of the man = the man's bike

However, when we are dealing with plurals, the apostrophe is added to indicate the possessive, but no "s" is needed anymore:

Ex. the skateboard of the guys = the guys' skateboard
