Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 13.903\% 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 additional words.
Options:
a CCOc1cc(/C=N/O)cc(Br)c1OC
b COC(=O)C1=NN(C(=O)c2ccc(C)cc2)C(O)(c2ccc(Cl)cc2)C1
c CCN1CCN(c2nc3c(C)cccn3c(=O)c2/C=C(\C#N)C(=O)NCCCOC)CC1
d CCC(=O)c1ccc(OCc2ccc(C(=O)OC)cc2)cc1
e CCOC(=O)C(=O)/C(C#N)=C/Nc1ccc(F)cc1
Answer: e. CCOC(=O)C(=O)/C(C#N)=C/Nc1ccc(F)cc1
