Task: Answer the multiple-choice question.
Question: Which compound exhibits a 5.543\% 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] O=C(COC(=O)CCC(=O)c1ccc(F)cc1)Nc1nnc(-c2ccccc2)o1
[b] O=C(Nc1ccc([N+](=O)[O-])cc1)c1cc(Cl)sc1Cl
[c] Cc1cc(C)c2nc(N3CCCN(C(=O)c4ccco4)CC3)c(C#N)cc2c1
[d] CS(=O)(=O)NC1CCN(Cc2ccccc2)CC1
[e] COc1cccc(-c2cc(C(F)(F)F)c(C#N)c(=O)[nH]2)c1
Answer: e. COc1cccc(-c2cc(C(F)(F)F)c(C#N)c(=O)[nH]2)c1
