The correct answer is C. went to France three weeks ago.
The sentence “Sue has been in France for the last three weeks” tells us that Sue is currently in France. This
means that she must have gone to France at some point in the past. The only option that describes a past event is C. went to France three weeks ago.Option A is incorrect because it uses the present progressive tense, which is used to describe actions that are happening right
now or that are happening repeatedly over time. Option B is incorrect because it uses the present perfect tense, which is used to describe actions that have happened or been completed in the past but have a connection to the present. Option D is incorrect because it uses the past perfect tense, which is used to describe actions that happened or were completed before another action in the past.
