Task: Answer the multiple-choice question.
Query: Which drug exhibits a 6.909% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
(a) O=S(=O)(NCc1cccnc1)c1ccc(Cl)s1
(b) Cc1cccc(OCc2nnc(SCC(=O)Nc3ccc(C)c(C)c3)o2)c1
(c) Cc1cc(C)cc(Nc2ccc([N+](=O)[O-])nc2[N+](=O)[O-])c1
(d) COc1cc2c(cc1NC(=O)CSc1nnc(Cc3cccs3)n1Cc1ccco1)oc1ccccc12
Answer: a. O=S(=O)(NCc1cccnc1)c1ccc(Cl)s1
