Problem statement: Answer the multiple choice question.
Question: Which drug has a 13.405\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a COc1ccc(NC(=O)c2ccc(S(=O)(=O)N3CCCCCC3)cc2)c(OC)c1
b COC(=O)C1=C(c2ccc(OC)c(OC)c2)C[C@@H]2CC[C@H]1N2C(=O)NCCOc1ccccc1Cl
c O=C(Nc1ccccc1)c1ccccc1N=Cc1ccccc1O
d O=C(c1ccccc1)c1c[nH]c(C(=O)NNc2cccc(Cl)n2)c1
Answer: c. O=C(Nc1ccccc1)c1ccccc1N=Cc1ccccc1O
