Task: Answer the multiple choice question.
Question: Which drug exhibits a 9.749\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
(a) CCn1cc(S(=O)(=O)CC(=O)Nc2cccc(C)c2)c2ccccc21
(b) CCOC(=O)C1=C(C)N=C2SCCC(=O)N2[C@@H]1c1cccs1
Answer: b. CCOC(=O)C1=C(C)N=C2SCCC(=O)N2[C@@H]1c1cccs1
