Task: Answer the multiple choice question.
Query: Which drug has a 12.012\% 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: O=c1cc(CN2CCN(c3ccccc3F)CC2)c2cc3c(cc2o1)CCCC3
b: O=C(O)CCNc1c([N+](=O)[O-])cc([N+](=O)[O-])c2ccccc12
Answer: b. O=C(O)CCNc1c([N+](=O)[O-])cc([N+](=O)[O-])c2ccccc12
