GMAT Critical Reasoning (CR) | Re: The Maxilux car company's design for its new luxury model,

Hi ,

I find choice D as less of a strengthener as we are not given whether Rubco will sell the replacement tyres at a higher price directly to consumers. If they sell the replacements to Maxilux directly , the profit will be approx zero as stated earlier.
Choice C in my opinion will cut down the Logistical and Transportation cost and help in increasing profits. Thus it makes the Rubco executives' claim more believable.

Experts , Any thoughts on this ?
