Task: Answer the multiple choice question.
Question: Which drug has a 6.770\% 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) COc1cc([N+](=O)[O-])ccc1NC(=O)Nn1cnnc1
(b) CSCCC(NC(=O)c1ccc(C(C)(C)C)cc1)C(=O)OCC(=O)N1CCCC1=O
Answer: a. COc1cc([N+](=O)[O-])ccc1NC(=O)Nn1cnnc1
