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.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
