Task: Answer the multiple choice question.
Question: Which drug has a 5.214\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
[a] O=C(Cc1nnc(NC(=O)Nc2ccc(Cl)cc2)s1)NCc1ccccc1
[b] O=C(Nc1cccc(-c2nc3ncccc3o2)c1)c1cc2ccccc2o1
Answer: b. O=C(Nc1cccc(-c2nc3ncccc3o2)c1)c1cc2ccccc2o1
