Is OA B ?

Here is how I did,
Testing the Idiom As many AS and doing comparison of frogs inhabit in Amazon to the Frogs inhabit in Australia

Hence B

EXPERTS PLEASE CORRECT ME IF I AM WRONG.

(A) as in
(B) as inhabit
(C) than are inhabitants of
(D) than does
(E) as opposed to in

In C and D, as many...than is unidiomatic.
Eliminate C and D.

Generally, as many as serves to compare CLAUSES.
In A and E, the usage of in seems to imply the following comparison:
Ten times as many frog species inhabit the Amazonian rain forests as [frog species inhabit] IN the Australian forests.
Since inhabit in is redundant, eliminate A and E.

The correct answer is B.

OA: Ten times as many frog species inhabit the Amazonian rain forests as inhabit the Australian forests.
Implied comparison:
Ten times as many frog species inhabit the Amazonian rain forests as [frog species] inhabit the Australian forests.
This comparison is logical.

yes, my mistake OA is indeed B
