Task: Answer the multiple choice question.
Question: Which compound has a 41.938% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
[a] O=c1c2ccccc2ncn1Cc1ccco1
[b] O=C(N/N=C/c1ccc[nH]1)c1ccccc1O
[c] CCOc1cc(CNCCO)cc(Br)c1OCc1ccccc1Cl.Cl
[d] CCC(=O)NC(=S)Nc1ccc(NC(=O)COc2ccc(Cl)cc2Cl)cc1
Answer: b. O=C(N/N=C/c1ccc[nH]1)c1ccccc1O
