sc-science-of-economics-43497.html

The science of economics, which for four decades was dominated by Keynesians, who at first stressed the government’s role in stimulating the economy, but who were ultimately led away from solutions based on government intervention.
(A) economics, which for four decades was
(B) economics that was to be
(C) economics, one which has, for four decades, been
(D) economics is one that for four decades has been
(E) economics, for four decades, is one that was

My question:
Doesn't the text in bold suggest that the Keynesians no longer dominate the economics. So we don't need a present continuous tense as in D.
Please advice.

Vertical split
was / has been --->
Between A and D. Comma + which is used for "optional" information hence I can write A as
The science of economics who at first stressed the government’s blah blah ----> who does not have antecedent now. Clearly A is wrong.

Now D.
The science of economics is one that for four decades has been ----> "is one" present tense. Its logical to connect present with present perfect. The belief that science of economics was dominated by Keynesians for four decades is still valid, so the use of present perfect "has been" is alright.

I will go with D, because it ensures that the scentence has a subject and verb by removing commas.
