Task: Answer the multiple choice question.
Query: Which compound exhibits a -1.641\% 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, or d without using any other words.
Options:
a) CC(=O)c1c(C)[nH]c(C(=O)COc2ccc(C#N)cc2)c1C
b) O=S(=O)(NC1CCCCC1Oc1ccccc1)c1ccccc1
c) COc1ccc(CNCc2cccc(OC)c2OC)cc1Br.O=C(O)C(=O)O
d) [O-]/C(=C(\C(=S)Nc1ccccc1F)[n+]1ccccc1)c1ccc(-c2ccccc2)cc1
Answer: c. COc1ccc(CNCc2cccc(OC)c2OC)cc1Br.O=C(O)C(=O)O
