Hi,
there is this question :
At nearly thirty-eight million dollars, one of the least costly options being considered, the delegate's proposal was ultimately rejected not only on account of its sizable budget but also on account of its considerable risk.
(A) At nearly thirty-eight million dollars, one of the least costly options being considered, the delegate's proposal was ultimately rejected not only on account of its sizable budget but also on account of its considerable risk.
(B) Even at nearly thirty-eight million dollars, the delegate's proposal was among the less costly options being considered; it was ultimately rejected not on account of its sizable budget but on account of its riskiness.
(C) The delegate's thirty-eight million dollar proposal, which was ultimately not rejected on account of its sizable budget but on account of its riskiness, had actually been one of the less costly options being considered.
(D) The delegate's thirty-eight million dollar proposal, nevertheless among the least costly options being considered, was ultimately not rejected on account of its sizable budget, but its riskiness.
(E) Ultimately rejected due not just to its sizable budget but also to its considerable risk, the delegate's proposal, even at thirty-eight million dollars, was one of the least costly options under consideration.
OA is B, but i don't understand why "less costly" is correct. Shouldn't it be "the least colstly".
We would say "among the most costly" and not "among the more costly" , wouldn't we?
Thanks in advance,
