Which line of code should be used to meet the rest of the tracking requirement?

An Adobe Analytic Developer needs to set s.campaign with the query string value whenever a query string of ?cid=[[value]] is present in the URL. The client does NOT want s.campaign to track duplicate values during the same visit to avoid tracking duplicate clickthroughs.

The developer has developed the following code in AppMeasurement:

s.campaign = s.Util.getQueryParam(‘cid’);

Which line of code should be used to meet the rest of the tracking requirement?
A . s.campaign = s.UtiLuniqueVal;
B . s.campaign = s.getValOnce(‘cid’)
C . s. campaign = s.UtilcookieRead(‘s_.campaign’);
D . s.campaign = s. getValOnce(s.campaign, ‘s_campaign’);
