Quick solution for this one: we see a lot of switching back and forth between "its" and "their" in the answer choices, where these pronouns refer to "Arcsun" and "Playlite". Arcsun and Playlite (along with other company names) are both singular nouns, so we need to match them with singular pronouns. A and C refer to Arcsun with "their", A, C, and D refer to Arcsun with "them", and A, B, and D refer to Playlite with "their". This leaves E as our only remaining option.
