Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 1.540\% 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)C1CCN(C(=O)CCNS(=O)(=O)c2cc(Br)cnc2N)CC1
b O=C(Cn1nc(-c2cccc(Cl)c2)ccc1=O)Nc1ccccc1Br
Answer: a. CCOC(=O)C1CCN(C(=O)CCNS(=O)(=O)c2cc(Br)cnc2N)CC1
