Task: Answer the multiple choice question.
Question: Which drug exhibits a -28.664\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a.) CCOC(=O)CSc1nnc(CNC(=O)c2cccs2)n1-c1cccc(C)c1
b.) CCCCC1=CC2=CC(=O)C(C)(OC(=O)CC)C(=O)C2=CN1CCc1ccc(Br)cc1
Answer: b. CCCCC1=CC2=CC(=O)C(C)(OC(=O)CC)C(=O)C2=CN1CCc1ccc(Br)cc1
