Choose the word that correctly completes the sentence. The security officers checked all bags and backpacks before allowing them inside the stadium. A. Spectators' B. Spectator's C. Spactatorses D. Spectators's

A.

Explanation:

The word "spectator" is both plural and possessive.  To pluralize, we add an "s" to get "spectators," and to make it possessive we add apostrophe "s".  However, the second "s" is not needed when the noun is plural, so we just add the apostrophe.
