Task: Answer the multiple choice question.
Question: Which compound exhibits a 13.095\% 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: O=C(Nc1ccccn1)c1cc2ccccc2o1
b: CC(=O)Nc1ccc(Nc2nc(-c3ccccc3)nc3ccccc23)cc1
c: CC(=O)C1=C(O)C(=O)N(CC(=O)O)C1c1ccccc1Cl
d: CO/N=C/c1c(-c2ccc(Cl)cc2)nc2cc(C)ccn12
e: CC1CCN(CC(=O)Nc2ccccc2C#N)CC1
Answer: e. CC1CCN(CC(=O)Nc2ccccc2C#N)CC1
