24 David _______ in that house for twenty years. A is living B lives C has lived

The correct answer is C 'has lived'. Explanation: The expression "for twenty years" is used to talk about a duration that started in the past and is still continuing in the present. This implies the use of the present perfect tense, which is represented here with 'has lived'. Option A ('is living') talks about what is currently happening, not the full duration. Option B ('lives') implies a habit or a current permanent state, not a duration. { "correct_answer": "C has lived" }
