Task: Answer the multiple choice question.
Question: Which compound has a 16.888\% 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, or c without using any other words.
Options:
[a] Cc1cccc(NC(=S)NCC2CCCO2)c1
[b] O=C(Nc1ccc(Br)cc1)c1ccccc1Br
[c] Cc1cc(C)nc(NC2=NCC(=O)N2c2ccc(Cl)cc2)n1
Answer: b. O=C(Nc1ccc(Br)cc1)c1ccccc1Br
