Task: Answer the multiple-choice question.
Question: Which compound exhibits a 8.732\% 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: CCCCC1=CC2=CC(=O)C(C)(OC(=O)CCC(=O)OC)C(=O)C2=CO1
b: CC(C)Cc1nc(SCC(=O)N2CCCC2)c2c(=O)n(C)c(=O)n(C)c2n1
c: O=C(NCc1ccccc1)c1cc[n+]([O-])cc1
Answer: a. CCCCC1=CC2=CC(=O)C(C)(OC(=O)CCC(=O)OC)C(=O)C2=CO1
