Out of scope.(B) There are still more cell phone users in the United States than China, despite the latter's greater population.
We are not interested in users of cell phones in US. We are concerned about Chinese cell phone market.(C) American companies still claim large shares of sales in China of other electronic devices such as computers.
Irrelevant(D) Many American cell phones are considered to be of superior quality to those produced by Chinese manufacturers.
Correct. This is the only choice that says something positive and relevant to the conclusion.
(E) Cell phones manufactured by Chinese companies use many imported electronic components.
