Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 7.999\% 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) Nn1c(Nc2ccccc2)nc2sc3c(c2c1=O)CCCC3
(b) O=C(COC(=O)COc1ccccc1)Nc1ncc([N+](=O)[O-])s1
Answer: b. O=C(COC(=O)COc1ccccc1)Nc1ncc([N+](=O)[O-])s1
