本题考查了第六段至第九段的事实细节。这四个段落提到了备选项中四个经济生产部门。第六段提到，消费品的生产几乎回到了一年前的水平，因为对汽车及其他物品的消费需求以及房屋产业在经济衰退期间都保持了健康发展。第七段提到，过去两个月的月住宅建筑和房产市场相关数据都在整个2001年的平均数以上。这表明住宅建筑有了好的开始，可能不会成为今年GDP增长的累赘。第八段提到，稳固的房产市场可以刺激对房屋相关物品和服务的需求，如家具、电子产品和纺织品。期望消费商品的产量在未来的月份里超越年前的水平。第九段提到，甚至办公设备部门的生产似乎都要降至最低点。它的产量因电脑设备0.6%的涨幅在1月上升了0.4%。
概括而言，汽车是消费者需求的对象，办公设备和电脑设备的产量只是小幅度的增长，只有房产市场不仅呈现良好发展势头，而且还带动其他生产领域的发展。因此［B］项正确。
