Task: Answer the multiple-choice question.
Question: Which drug exhibits a -3.001\% human ether-à-go-go related gene (hERG) inhibition at 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(SCC(=O)N2N=CCC2c2ccccc2)cc1
b: Cc1ccc(Cn2c(CN3CCOCC3)nc3c2c(=O)n(C)c(=O)n3C)cc1
c: COc1ccc(Cc2nc(-c3ccc(Br)o3)no2)cc1OC
d: CN(C)S(=O)(=O)c1ccc(C(=O)Nc2nnc(-c3ccc4c(c3)CCCC4)o2)cc1
e: COc1ccc(OC)c(C2C(C(C)=O)=C(O)C(=O)N2c2ccc(F)cc2)c1
Answer: c. COc1ccc(Cc2nc(-c3ccc(Br)o3)no2)cc1OC
