Task: Answer the multiple choice question.
Query: Which compound exhibits a 4.700\% 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 additional words.
Options:
a. CC(C)C(c1nnnn1C(C)(C)C)N1CCOCC1
b. COC1=C(Nc2ccccc2)C(=O)c2ccccc2C1=O
c. CC(C)COc1ccc(C(=O)Nc2scc(-c3ccc(Cl)cc3Cl)c2C(N)=O)cc1
d. CCN(CC(=O)Nc1ccc(OC)cc1)C(=O)c1ccc(Cl)c(S(=O)(=O)N2CCCC2)c1
e. O=C(CSc1nnc(Nc2ccccc2F)s1)Nc1cccc(S(=O)(=O)N2CCCCC2)c1
Answer: a. CC(C)C(c1nnnn1C(C)(C)C)N1CCOCC1
