Task: Answer the multiple choice question.
Question: Which drug has a -1.393\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a) COc1ccccc1C1=NOC(C(=O)N2CCN(C(=O)c3ccco3)CC2)C1
b) CC(C)(C)c1nn2cnnc2n(/N=C/c2ccc(O)cc2)c1=O
Answer: b. CC(C)(C)c1nn2cnnc2n(/N=C/c2ccc(O)cc2)c1=O
