Task: Answer the multiple-choice question.
Question: Which drug exhibits a -20.908% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a. O=C(COC(=O)C1CCN(/C=C/C(=O)C(F)(F)F)CC1)Nc1cccc(F)c1
b. COc1cc2c(cc1NC(=O)c1cccnc1)oc1ccccc12
Answer: a. O=C(COC(=O)C1CCN(/C=C/C(=O)C(F)(F)F)CC1)Nc1cccc(F)c1
