Task: Answer the multiple-choice question.
Query: Which compound exhibits a 3.766\% 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 additional words.
Options:
[a] C=CCNc1nc(NCc2ccccc2)c(C#N)c2c1CN(C)CC2
[b] CC(Sc1ccc2ccccc2c1)C(=O)NC(N)=O
[c] COc1ccc(S(=O)(=O)NCCOc2ccccc2)cc1OC
[d] Cc1ccc(Cn2c(C(=O)O)cc3sccc32)cc1
[e] O=C(O)COc1ccc(Oc2ccccc2)cc1
Answer: c. COc1ccc(S(=O)(=O)NCCOc2ccccc2)cc1OC
