Task: Answer the multiple-choice question.
Question: Which compound exhibits a -20.853\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a CCc1nc(SCC(=O)c2ccc(C)c(C)c2)n[nH]1
b CSc1cc(C)n(-c2ccc(Cl)cc2)c(=S)c1C(C)=O
c O=C(CN1C(=O)/C(=C/c2ccco2)SC1=S)Nc1ccc(O)c(C(=O)O)c1
Answer: b. CSc1cc(C)n(-c2ccc(Cl)cc2)c(=S)c1C(C)=O
