The cost of this conversion would be the same whether done at the logging site, where the trees are debranched, or at United's factory. However, wood chips occupy less than half the volume of the branches from which they are made.

a) logically inferred
b) is completely supported by argument w/o any help from the outside the passage

(A) Converting the branches into wood chips at the logging site would require transporting a fully assembled wood-chipping machine to and from the site. < not talk of machines >
(B) It would be more economical to debranch the trees at the factory where the fiberboard is manufactured. < does the argument support this? no>
(C) The debranching of trees and the conversion of the branches into chips are the only stages in the processing of branches that it would be in United's economic advantage to perform at the logging site. <there is not talk about stages>
(D) Transportation costs from the logging site to the factory that are determined by volume of cargo would be lower if the conversion into chips is done at the logging site rather than at the factory. <we can infer that if volume is reduced then more stuff can be taken in fewer trips>
(E) In the wood-processing industry, branches are used only for the production of wood chips for fiberboard. <nice insight but not useful>
