Task: Answer the multiple choice question.
Query: Which drug exhibits a 10.556\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a O=C(COc1coc(CN2CCN(c3ccc(F)cc3)CC2)cc1=O)Nc1ccccc1
b O=C(CCOc1ccccc1)Nc1ccnn1C1CCN(Cc2ccc(CO)o2)CC1
Answer: a. O=C(COc1coc(CN2CCN(c3ccc(F)cc3)CC2)cc1=O)Nc1ccccc1
