Step-by-step explanation:
The plant that is woody, bottle-shaped, ends at the top with tufts of foliage, and can improve air quality in the home of smokers is most likely to be a type of palm. Palms are known for their distinctive shape, and some varieties are praised for their air-purifying qualities. While this description does not perfectly fit any of the given options, palms are often associated with these characteristics. It's important to note that in terms of air-purifying plants, other species such as peace lilies, snake plants, and spider plants are also highly effective according to NASA's Clean Air Study, but they are not described as woody or bottle-shaped.
