Problem statement: Answer the multiple choice question.
Query: Which drug has a 13.484\% 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(Nc1ccc([N+](=O)[O-])cc1)c1cc(-c2ccccn2)nc2c(Cl)cccc12
[b] O=C(COc1ncnc2ccc(Br)cc12)NC1CCCC1
Answer: a. O=C(Nc1ccc([N+](=O)[O-])cc1)c1cc(-c2ccccn2)nc2c(Cl)cccc12
