Task: Answer the multiple choice question.
Question: Which drug exhibits a 8.135% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: COc1ccccc1C(c1nnnn1CC1CCCO1)N1CCC(C(N)=O)CC1.Cl
b: O=C(c1ccc(-c2ccccc2Cl)o1)N1CCN(c2ccccc2O)CC1
c: CC(OC(=O)COc1ccc(C#N)cc1)C(=O)Nc1ccc(Cl)cn1
d: O=C(NC1CC1)C1=C[C@H](c2coc3ccccc3c2=O)C[C@H](OCc2ccc(CO)cc2)O1
e: CSc1nc(N)nc(C2CC2)n1
Answer: e. CSc1nc(N)nc(C2CC2)n1
