Filamentous organisms are often fungi or some types of algae, but the absence of chloroplasts rules out the latter. Since the organism has a cell wall, it is not classified as an animal, which leaves fungi as the most likely option. The lack of chloroplasts also rules out the Plantae kingdom, making the correct answer choice E, which is domain Eukarya, kingdom Fungi.
