Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 15.893\% human ether-à-go-go related gene (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 other words.
Options:
[a] Cc1ccc(C2C3=C(CCCC3=O)OC3=C2C(=O)CCC3)cc1
[b] Cc1ccc(NC(=O)c2cccc(NC(=O)Cc3ccccc3)c2)cc1
[c] COc1cc2oc3ccccc3c(=O)c2cc1OC
[d] CCOC(=O)C1=CCN(Cc2ccccc2)CC1.Cl
[e] O=c1[nH]c(NC2CCCCC2)c([N+](=O)[O-])c(=O)[nH]1
Answer: e. O=c1[nH]c(NC2CCCCC2)c([N+](=O)[O-])c(=O)[nH]1
