Task: Answer the multiple choice question.
Question: Which drug exhibits a -6.949% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: COc1ccccc1C(=O)NNC1=C(C(=O)C(F)(F)F)CCC1
b: O=C(CSCc1nc2ccccc2[nH]1)Nc1ccc(Oc2ccccc2)cc1
Answer: b. O=C(CSCc1nc2ccccc2[nH]1)Nc1ccc(Oc2ccccc2)cc1
