Task: Answer the multiple-choice question.
Query: Which compound exhibits a 11.989\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: CC(=O)C1=C(C)OC(N)=C(C#N)C1c1cccc([N+](=O)[O-])c1
b: COc1ccccc1[C@@H]1C(c2cccc(Cl)c2)=NN(c2ccc(Br)cc2)[C@H]1C(=O)N1CCOC1=O
c: Cn1ncc(C(N)=O)c1NC(=S)NC(=O)c1ccc(Br)o1
d: O=C(COC(=O)c1ccc2ccccc2n1)c1ccccc1
e: O=C(NC1CCCCC1)c1cc(C2CC2)on1
Answer: a. CC(=O)C1=C(C)OC(N)=C(C#N)C1c1cccc([N+](=O)[O-])c1
