Task: Answer the multiple choice question.
Query: Which drug exhibits a 12.213\% 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, c, d, or e without using any other words.
Options:
a COc1ccc(C2(CNC(=O)C(=O)Nc3ccc(C)cc3)CCOCC2)cc1
b COCCn1c(SCc2nc3cc(OC)c(OC)cc3c(=O)[nH]2)nnc1-c1ccncc1
c COc1ccc(NC(=O)CSc2sc3c(O)cc(=O)[nH]c3c2C#N)c(OC)c1
d CC(=O)c1ccc([C@H]2C[C@@]34CN(C(=O)OC(C)(C)C)S(=O)(=O)[C@H]3C[C@H]2O4)cc1
e CC1CCCN(C(=O)CSc2nnc(-c3ccncc3)n2C)C1
Answer: c. COc1ccc(NC(=O)CSc2sc3c(O)cc(=O)[nH]c3c2C#N)c(OC)c1
