This means, in the case presented all words should be capitalized, this includes "Merryhill Road", "Huntington" and "Virginia" but also the words "South" and "West" because they are part of proper names and refer to specific regions. Thus, the correct answer is "350 South Merryhill Road, Huntington, West Virginia".
