Choose the option that best completes the gap(s).

When we looked up, we _____ the plane some miles away?

Answer Details

The option that best completes the sentence is "sighted." This is because the context of the sentence suggests that the speaker saw an airplane some miles away, so the past tense of the verb "to sight" (meaning to see or catch sight of) should be used. The other options ("site," "cited," and "sited") are not correct because they have different meanings that do not fit the context of the sentence.
