Task: Answer the multiple choice question.
Question: Which drug exhibits a 12.590% 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. COc1cc(/C=C(/C#N)C(=O)NCc2ccccc2)cc(OC)c1OC
b. N#C/C(=C\N1CCCCC1)S(=O)(=O)c1ccc(Cl)cc1
c. N#C/C(=C1/C(=O)Nc2ccc(Br)cc21)c1ccccn1
d. CC(C)(C)c1nc(SCC(=O)N2CC(=O)Nc3ccccc32)c2ccccc2n1
e. C/C(=N\NC(=O)Cc1ccc([N+](=O)[O-])cc1)c1cccnc1
Answer: c. N#C/C(=C1/C(=O)Nc2ccc(Br)cc21)c1ccccn1
