Task: Answer the MCQ question.
Question: Which drug exhibits a 2.162\% human ether-à-go-go related gene (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)C/C(C)=N/NC(=O)CNc1cccc(Cl)c1C
b.) Cc1ccccc1CN(c1ccc(C(=O)N2CCc3ccccc3C2)cc1)S(C)(=O)=O
Answer: a. CCOC(=O)C/C(C)=N/NC(=O)CNc1cccc(Cl)c1C
