Task: Answer the multiple choice question.
Query: Which compound exhibits a 12.754\% 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) Cc1ccc(N2C(=O)c3ccc(C(=O)N4CCOCC4)cc3C2=O)cc1C
b) O=C(OCc1nc2ccccc2[n+]([O-])c1C(=O)c1ccccc1)c1ccco1
c) CCOC(=O)/C(=N\Nc1ccccc1[N+](=O)[O-])c1csc(Nc2ccccc2)n1
d) CCOc1ccccc1Nc1nnc(SCc2ccc(C(=O)OC)o2)s1
e) COc1ccc(Cc2nnc(Nc3ccccc3)s2)cc1Br
Answer: e. COc1ccc(Cc2nnc(Nc3ccccc3)s2)cc1Br
