Task: Answer the multiple choice question.
Question: Which compound has a 8.089\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: CCOC(=O)Cc1c(C)nc2c(-c3ccc(Cl)cc3)c[nH]n2c1=O
b: CCOC(=O)c1ccc(Nc2nnc(C(C)(C)C)c(=O)[nH]2)cc1
c: Cc1ccc(C)c(S(=O)(=O)NCc2ccc(C(=O)N3CCOCC3)cc2)c1
d: O=C1Nc2ccc([N+](=O)[O-])cc2OC1CCN1CCN(c2ccccc2)CC1
e: S=C(Nc1cccc(Cl)c1)N(CCCN1CCCC1)Cc1cccn1Cc1ccc(Cl)cc1
Answer: a. CCOC(=O)Cc1c(C)nc2c(-c3ccc(Cl)cc3)c[nH]n2c1=O
