Task: Answer the multiple choice question.
Query: Which compound has a 9.029\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] CCn1c(CNC(=O)c2cccc(C)c2)nc2ccccc21
[b] O=[N+]([O-])c1ccc(/C=N/Nc2ncccc2[N+](=O)[O-])s1
[c] COCCn1c(=O)[nH]c2cc(C(=O)NCCN3CCN(c4ccc(OC)cc4)CC3)ccc2c1=O
[d] O=C(O)c1cc2n(n1)CCN(Cc1ccccc1Cl)C2=O
Answer: a. CCn1c(CNC(=O)c2cccc(C)c2)nc2ccccc21
