Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 1.516% 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) CCOC(=O)c1cc2c(=O)n3cccc(C)c3nc2n(CCCOC)c1=NC(=O)c1cccnc1
b) CCOC(=O)C1=C2N(C)c3ccccc3N2CCC1=O
c) O=S1(=O)N=CN(Cc2cccc(F)c2)c2ccccc21
d) CN(Cc1ccccc1)C(NC(=O)c1ccccc1)C(Cl)(Cl)Cl
Answer: b. CCOC(=O)C1=C2N(C)c3ccccc3N2CCC1=O
