Task: Answer the multiple choice question.
Question: Which compound has a 15.255\% 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. Cc1nc(SCCc2ccccc2)[nH]c(=O)c1C
b. COC(=O)c1c(NC(C)=O)sc(C(=O)Nc2ccccc2OC)c1C
c. CC(NC(=O)CC12CC3CC(CC(C3)C1)C2)C(=O)O
d. O=C(NCc1ccccc1)NC12CC3CC(CC(C3)C1)C2
Answer: b. COC(=O)c1c(NC(C)=O)sc(C(=O)Nc2ccccc2OC)c1C
