Problem statement: Answer the multiple-choice question.
Question: Which compound exhibits a 20.067\% 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: CN1CCc2nc(SCC(=O)Nc3cccc(F)c3)c(C#N)c(-c3cccs3)c2C1
b: Cc1ccc(NC(=O)c2cccc(OCc3c(C)noc3C)c2)cc1
c: O=C(Nc1ccncc1)Nc1ccc(F)cc1F
d: COc1ccc(Cl)cc1C(=O)NNC(=S)NC(=O)/C=C/c1ccco1
e: CN(C)/C=C1\C=C(c2ccccc2)OC1=O
Answer: c. O=C(Nc1ccncc1)Nc1ccc(F)cc1F
