Task: Answer the multiple choice question.
Query: Which compound has a 17.058\% 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: COc1ccccc1OCc1nnc(SCC(=O)Nc2ccc(C)cc2)n1C
b: COc1cc(-n2c(=O)c3ccccc3n(Cc3cccnc3)c2=O)cc(OC)c1OC
c: Cn1ncc2c(Nc3ccccc3Br)ncnc21
d: CCOC(=O)CN1C(=O)C(O)=C(C(C)=O)C1c1ccccc1
e: CCCNC(=O)c1nnsc1Sc1ccc(Cl)cc1
Answer: c. Cn1ncc2c(Nc3ccccc3Br)ncnc21
