Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 1.964\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
[a] CC(=O)c1cc2c(cc1NC(=O)CSc1nc3ccccc3[nH]1)OCO2
[b] O=C(CS(=O)(=O)c1ccccc1)Nc1ccc(S(=O)(=O)Nc2ccccn2)cc1
Answer: b. O=C(CS(=O)(=O)c1ccccc1)Nc1ccc(S(=O)(=O)Nc2ccccn2)cc1
