Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 8.356\% human ether-à-go-go related gene (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] COc1ccc(-n2nc([N+](=O)[O-])c(=NCCc3cccc(C)c3)n2O)cc1
[b] Nc1nc2nccc(-c3cccnc3)n2n1
[c] COCCCn1c(=O)c2ccccc2n(Cc2ccccc2C)c1=O
[d] CCC(=O)Nc1cccc(Oc2nc(C)cc(C)c2C#N)c1
[e] COC(=O)C1=C(N)c2c(F)cccc2C1(C#N)c1ccc(F)cc1
Answer: a. COc1ccc(-n2nc([N+](=O)[O-])c(=NCCc3cccc(C)c3)n2O)cc1
