English · Subject Verb Agreement

The sentence "One of my sisters is going on a trip to France" refers to a single sister out of a group of sisters. Since it is referring to one sister, the singular form of the verb "is" should be used. Option A, "Is," is the correct choice in this case.

Options B, C, and D are incorrect because they use plural forms of the verb, which do not agree with the subject "one sister." "Are" is the plural form of "is," "has" is the singular form of "have," and "have" is also the plural form of "has." Since the subject is singular, only the singular form "is" is appropriate.
