SC: Value of dollar

[laveshdixit]

Source: GmatClub
The value of the dollar in international markets will continue to increase, as it has been since interest rates began to rise.
(A) as it has been
(B) as it has done
(C) which it has
(D) which it has been
(E) which it had been

I felt that A was the correct answer, since it implies that the dollar was on the rise and will continue the trend.
I am not sure of what the correct answer is for the question.

Please help.
