Founded in 1983, the magazine increased its circulation more than double since then, and its advertising.

[A] increased its circulation more than double since then,

has since increased its circulation more than double,

[C] has since more than doubled its circulation

[D] since then more than doubled its circulation

[E] more than doubled its circulation since then


The given OA is C.

I came down to the options C and D. Option D seems to be a more lucrative option in this case.

simple past tense and present perfect tense - what is the difference between the two...

I feel the correct answer can be any of the two.

IMO SINCE THEN can be used only for PERFECT tense (not for past) and therefore D is wrong
