Task: Answer the multiple choice question.
Question: Which compound has a 8.114\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: O=C1CC(Sc2nnnn2-c2ccccc2)C(=O)N1c1cccc(Cl)c1
b: CCc1cc(C(=O)Cc2cnn(-c3ccccc3)c2)c(O)cc1O
c: Nc1nc(SCC(=O)C23CC4CC(CC(C4)C2)C3)n[nH]1
d: O=C(Nc1cccc([N+](=O)[O-])c1)c1ccc2c(c1)OCCO2
Answer: a. O=C1CC(Sc2nnnn2-c2ccccc2)C(=O)N1c1cccc(Cl)c1
