Answer 2

Answer:

Since 2003 they have visited their son every year.

Explanation:

• In English, tenses play a major role in expressing the time reference of any event or action.

• Both 'present perfect' and 'present perfect continuous' are used in situational circumstances based.

• We use the 'present perfect ' or the perfect when we are thinking about the past and present time at the same time ( Past and now).

• They have visited = present perfect. They began visiting their son in 2003 they are still doing that visit every year i.e. at a usual frequency (indicated by the past article "ed" visit-ed.

• They have been visiting = the present perfect continuous used to look back over actions in the past and situations in the present i.e. at an unusual frequency/ interval.

• They began visiting in 2003 and they will and are continuing to visit now. 'visit+ing' signifies a continuing action that has started in the past and is still going on in this sentence.

Hence the correct verb form is 'have visited.'
