[senthil]

is OA C?

[loki.gmat]

we require "that" here after "Bethlehem Steel" as that would refer to "integrated companies".
so A n E r out.

also after the line "The steel industry has changed radically over the last two decades" we require "as" here bcoz the author wants to convey the reasons (greatly downsized or shut down) for the radical change in the steel industry.

hence IMO B.
