Task: Answer the multiple choice question.
Question: Which drug exhibits a 11.442\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a) O=C(NCc1cccc(C(F)(F)F)c1)C1CCN(c2ncccn2)CC1
b) O=C(NC(=S)Nn1cnc2c(cnn2-c2ccccc2)c1=O)c1ccc(Cl)cc1
Answer: b. O=C(NC(=S)Nn1cnc2c(cnn2-c2ccccc2)c1=O)c1ccc(Cl)cc1
