Task: Answer the multiple-choice question.
Question: Which drug exhibits a 7.887\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a. COc1ccc(NC(=O)CSc2nc3ccccc3nc2N2CCOCC2)c(OC)c1
b. CCOC(=O)/C=C1\SCC(=O)N1CC(=O)Nc1ccc2c(c1)CCC2
c. O=C(CN1CCN(c2ccccn2)CC1)Nc1ccc(Oc2ccccc2)cc1
Answer: c. O=C(CN1CCN(c2ccccn2)CC1)Nc1ccc(Oc2ccccc2)cc1
