Question No : 7
This item will ask you to determine the missing code.
In the data shown below, each record represents a single treatment period and contains a character SUBJID and non-missing numeric dates EXSTDT and EXENDT.
The Duration of Treatment (in days) for a single period is defined as Treatment End Date - Treatment Start Date + 1. For each subject, the Total Duration (in days) is defined as the sum of durations of treatment across all treatment periods.



Which code segment generates the new data set, EX2, which contains a single record per subject and includes the Duration of Treatment?
data EX2
set EX;
by subjid exstdt exendt;
<insert code here>
run;

• A.duration = exendt - exstdt + 1; TotalDur = TotalDur + duration; if first.subjid then TotalDur = duration; if last.subjid;
• B.retain TotalDur; duration = exendt - exstdt + 1; TotalDur = TotalDur + duration; if first.subjid then Totaldur = duration; if last.subjid;
• C.retain TotalDur; duration = exendt - exstdt + 1; TotalDur = TotalDur + duration; if first.exstdt then TotalDur = duration; if last.exstdt;
• D.duration = exendt - exstdt + 1; TotalDur = TotalDur + duration; if first.exstdt then TotalDur = duration; if last.exstdt;
