Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a -0.155\% 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 additional words.
Options:
a) O=c1[nH]n2c(=O)c3c([nH]c2c1N=Nc1cccc(Cl)c1)CCC3
b) COc1ccc(C2C(C(=O)c3cccs3)=C(O)C(=O)N2c2cccc(C)n2)cc1OC
c) Cc1ccc(CNC(=O)c2sccc2C)cc1
d) Oc1c(N=NC(=S)Nc2ccccc2F)c2ccccc2n1Cc1ccccc1F
Answer: b. COc1ccc(C2C(C(=O)c3cccs3)=C(O)C(=O)N2c2cccc(C)n2)cc1OC
