Which sentence demonstrates the correct use of an apostrophe?

a) a sea star is an echinoderm because it’s body has five sections that are arranged around a central disk.
b) sea star’s spines are made of calcium carbonate plates, which protect the creature from birds, fish, and sea otters.
c) close observers will notice that, though sea stars appear to float, they’re actually propelled by tiny tube feet.
d) sea stars have an amazing ability to drop their arms when threatened by a predator—but then regenerate new one’s.

The answer to the question above would be that the sentence that demonstrates the correct use of the apostrophe is the following one: "Close observers will notice that though sea stars appear to float, they're actually propelled by tiny tube feet". That is, your answer would be C.

In A, the determiner "its" should not have an apostrophe because it is the possessive determiner. In B, the apostrophe should be after the -s because the noun is plural, the sentence is a generalization saying something as regards all sea stars. Finally, with respect to D, it could be said that it also should be after the -s because "ones" refers back to "sea stars", which is a plural noun.
