Task: Answer the multiple choice question.
Question: Which drug exhibits a 15.171\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
[a] COc1ccc(CCC(=O)Nc2ccc3c(c2)OCO3)cc1
[b] O=C(COC(=O)c1cccs1)NCCN1C(=O)CSC1=O
[c] O=C(c1cc2n(n1)C(C(F)(F)F)CC(c1ccco1)N2)N1CCN(c2ccccn2)CC1
[d] COC(=O)c1sccc1NC(=S)N1CCCC(C)C1
Answer: b. O=C(COC(=O)c1cccs1)NCCN1C(=O)CSC1=O
