Option(B) is correct
Option A : An increase in expenditure on packing material and labor might affect the company's profitability, but it would have no effect on whether items were damaged in transit.
Option B : Correct. This statement adequately explains why more items, rather than fewer, were damaged in transit.
Option C : If customers were able to remove their items just as easily from boxes filled with more packing material as from boxes usingless packing material, the items would be unaffected by an increase in the amount of packing material used.
Option D : The kind of goods True Save ships most frequently isnot relevant to the question of why increasing the amount of packing material failed to reduce the number ofitems damaged in transit, since they most likely shipped this same kind of goods both before and after making the recommended change.
Option E : The loss of regular customers helps explain why TrueSave turnedto the packaging consultants for help, but it does not help explain why those consultants' recommendation failed to reduce the number of items damaged in transit.
The correct answer is B.
