Task: Answer the multiple choice question.
Question: Which compound has a -1.669\% 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) CCC1Nc2ncnc(N3CCN(c4ccccc4)CC3)c2N(Cc2ccc(C)cc2)C1=O.O=C(O)C(F)(F)F
b) CC(=O)C(Sc1nccc(-c2cccs2)n1)C(C)=O
c) COc1ccc(CNC(=O)c2cccc3c2C(=O)N(CC2CCCO2)C3)cc1
Answer: b. CC(=O)C(Sc1nccc(-c2cccs2)n1)C(C)=O
