Task: Answer the multiple choice question.
Query: Which drug exhibits a -1.089\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a. O=C(COc1coc(CN2CCN(c3ccccc3F)CC2)cc1=O)N1CCc2ccccc21
b. C=CCn1cnc2c(nnn2-c2ccc(C)c(Cl)c2)c1=O
Answer: a. O=C(COc1coc(CN2CCN(c3ccccc3F)CC2)cc1=O)N1CCc2ccccc21
