Task: Answer the multiple choice question.
Query: Which compound exhibits a 14.390% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
[a] COC(=O)Cc1c(C)nc2nc[nH]n2c1=O
[b] COc1ccc(C(=O)c2c(-c3ccsc3)oc3ccc(-c4ccc(OC)cc4)cc23)cc1
[c] O=C(c1cccc(C(=O)N2CCN(c3ncccn3)CC2)c1)N1CCN(c2ncccn2)CC1
[d] O=C(Nc1cccc([N+](=O)[O-])c1)C1CCN(C(=O)Cc2ccccc2)CC1
[e] COCCNC(=O)C(c1ccc(Cl)cc1)N(CCOC)C(=O)CCC(=O)Nc1nccs1
Answer: a. COC(=O)Cc1c(C)nc2nc[nH]n2c1=O
