Task: Answer the multiple-choice question.
Query: Which compound exhibits a 5.647\% 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] CCCCCC(=O)Nc1ccc(N2CCOCC2)c(S(=O)(=O)Nc2ccc(OC)cc2)c1
[b] CC(=NCCN1CCOCC1)c1c(O)n(C2CCCCC2)c(=O)[nH]c1=O
[c] CC(C)CCn1c(N2CCc3ccccc3C2)nc2c1c(=O)[nH]c(=O)n2C
[d] Oc1ccc(/C=N/Nc2nc(N3CCCC3)nc(N3CCCC3)n2)cc1O
[e] COc1ccc(C2C(C#N)=C(N)Oc3cc(C)[nH]c(=O)c32)cc1OC
Answer: e. COc1ccc(C2C(C#N)=C(N)Oc3cc(C)[nH]c(=O)c32)cc1OC
