Task: Answer the multiple choice question.
Question: Which compound has a 10.917\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
[a] O=C(N/C(=C/c1ccc(Br)cc1)C(=O)N1CCCC1=O)c1ccco1
[b] C=CCc1cccc2cc(C(=O)NCCOC)c(=O)oc12
[c] COc1ccc(OC)c(NC(=S)NCc2cccnc2)c1
[d] O=C(CSc1nnnn1-c1ccc(O)cc1)Nc1cccc(S(=O)(=O)N2CCCC2)c1
Answer: b. C=CCc1cccc2cc(C(=O)NCCOC)c(=O)oc12
