There are only two potential candidate for the correct choice are choice C and choice D.

In the non-underlined part, the study focused (simple past). So the subjects of the studies must "had smoked", smoking before the study progress.

So, choice D is the correct one.

E. group: 53,000 current and former heavy smokers, who were aged 55 to 74,and who had smoked for higher than at least 30 pack‐years

Between C and D, have to go with D. The past perfect seems necessary.

who smoked for atleast 30 pack years, clearly shows it is preceding the selection, hence I feel there is no need for past perfect..
My Choice is C, but fingers crossed..

aging from is incorrect =? Eliminate A , Who were aged seems to suggest somebody aged them and it was not a natural process => Eliminate E. that is not the correct pronoun here = > Eliminate B .Since this sentence talks about a study which definitely occurred in the past we need past perfect to establish a time sequence here. D wins.

+1 D

OE
A – "aging" distorts the meaning of the sentence. The use of "which' is incorrect.
B – "that" incorrectly refers to "smokers", the correct pronoun should be "who".
C – We need the past perfect tense "had" since the sentence talks about two things occurring at different time periods in the past
E – awkward and wordy construction. Use of "higher than" is also awkward

Hi
Shouldn t it even be "...who ve been smoking..."??
To me D seems wrong as well...
Because it says current and former so the action still continues for some of the group.

Yes but here you arr using current and former, so we need to determine whats true for both, for former smokers its not true they have been smoking, and for current smokers who had smoked is also true and who have been also true. So the overlapping part should be considered.

D,

I came down to D and E.

D. group: 53,000 current and former heavy smokers, aged 55 to 74, who had smoked for at least 30 pack‐years
E. group: 53,000 current and former heavy smokers, who were aged 55 to 74,and who had smoked for higher than at least 30 pack‐years

E seems wrong, because "higher than" and "least" will not go along.
Either you say higher than X or at least X.

My original answer was B, but after reviewing I see why D is the correct answer.

A. Wrong, the group of heavy somkers cannot be aging from 55 to 74.
B. Wrong, cannot use "that" when referring to people.
C. Wrong, "had" is required because the study was already done in the past and the smokers have already been smoking.
D. Correct
E. Wrong, I believe there is a modification error, the item following "heavy smokers" must be re-latable to that group.
