Task: Answer the multiple choice question.
Query: Which drug exhibits a 13.268\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
(a) COc1cccc(/C=N/NC(=O)CCCC(=O)Nc2ccc(Br)cc2)c1
(b) CCOC(=O)N1CCN(C(=O)c2ccc3c(Cl)c4c(nc3c2)CCCC4)CC1
(c) C=CCN(C(=O)CCC(=O)Nc1cc(C)on1)C(C(=O)NC(C)(C)C)c1cccc(OC)c1OC
(d) Cc1cccc(NC(=O)c2ccc(S(=O)(=O)N3CCCCC3)cc2)n1
Answer: c. C=CCN(C(=O)CCC(=O)Nc1cc(C)on1)C(C(=O)NC(C)(C)C)c1cccc(OC)c1OC
