Answer:
Explanation: The sentence that contains a plural spelling error is:
B.) Several man helped to lift and move the refrigerator.
The error in this sentence is the incorrect use of "man" instead of the plural form "men." The correct sentence should be "Several men helped to lift and move the refrigerator."
The word "man" is singular, referring to one individual, while "men" is the plural form, referring to multiple individuals. In this sentence, since the subject is "Several," indicating more than one person, the plural form "men" should be used to match the subject.
