Task: Answer the multiple choice question.
Question: Which drug exhibits a 14.509% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
[a] Cc1cc(OCC(=O)N2CCCCCC2)ccc1[N+](=O)[O-]
[b] COc1ccc(N2CC(C(=O)N[C@H](C(=O)NC3CCCCC3)C(C)C)CC2=O)cc1
Answer: b. COc1ccc(N2CC(C(=O)N[C@H](C(=O)NC3CCCCC3)C(C)C)CC2=O)cc1
