Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The sentence uses 'for the last eight years', which indicates a duration leading up to the present. This requires the present perfect continuous tense: 'have been living'. 'Are living' is present continuous and does not correctly express a duration starting in the past.
