Task: Answer the multiple choice question.
Question: Which drug has a -23.684\% 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] COc1ccc(NC(=S)NCC(c2cccnc2)N2CCOCC2)cc1
[b] COCCN1C=C2C(=O)C(C)(OC(=O)CCc3ccccc3)C(=O)C=C2C=C1c1ccc(C#N)cc1
[c] O=c1ccc(Cl)cn1Cc1ccccc1F
Answer: b. COCCN1C=C2C(=O)C(C)(OC(=O)CCc3ccccc3)C(=O)C=C2C=C1c1ccc(C#N)cc1
