Building Large hospitals

[goelmohit2002]

Hi All,

In the below question, the OA is [spoiler]"E"[/spoiler]. Can somebody please help me understand the same ? The OA looks to be totally awkward to me.

Building large new hospitals in the bistate area would constitute a wasteful use of resources, on the basis of avoidance of duplicated facilities alone.

(A) on the basis of avoidance of duplicated facilities alone
(B) on the grounds of avoiding duplicated facilities alone
(C) solely in that duplicated facilities should be avoided
(D) while the duplication of facilities should be avoided
(E) if only because the duplication of facilities should be avoided

Thanks
Mohit

The construction presents in E "if only because.." is the only one having the meaning of "this is a reason sufficient to avoid the duplication of hospitals". There may be or not be other reasons, but this reason alone is sufficient.
The other choices fail to convey this meaning.

Aren't "A", "B" and "C" conveying the same thing ?
