Task: Answer the multiple-choice question.
Query: Which drug exhibits a -13.127\% 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 other words.
Options:
a O=C(Cc1ccc(Cl)cc1Cl)Nc1cccc(S(=O)(=O)Nc2ccccc2F)c1
b O=C(CSc1nnc(-c2ccccn2)n1Cc1ccccc1)N1CCCC1
c Cc1cc(C)n(Cc2ccc(NC(=O)c3c([N+](=O)[O-])c(C)nn3C)cc2)n1
d CCOC(=O)C1CCN(C2=NC(=O)/C(=C/c3ccc(Cl)cc3)S2)CC1
Answer: d. CCOC(=O)C1CCN(C2=NC(=O)/C(=C/c3ccc(Cl)cc3)S2)CC1
