Cocaine's primary metabolite detected in urine drug screens is which?

Explanation:
Cocaine exposure is detected in urine mainly by measuring its primary metabolite, benzoylecgonine. After cocaine is taken, it is rapidly metabolized, and benzoylecgonine is formed and excreted in urine in relatively higher and longer-lasting amounts than the parent drug. This makes benzoylecgonine a stable and reliable marker for cocaine use in screening assays. The other substances listed are not cocaine metabolites, as they come from different drugs with separate metabolic pathways.
