Task: Answer the multiple choice question.
Question: Which drug exhibits a -49.047% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: Cc1cc(NCc2ccco2)nc(N2CCC(C(=O)NC3CCCCC3)CC2)n1
b: O=C(COC(=O)C1CCN(S(=O)(=O)c2cccs2)CC1)Nc1ccccc1Br
Answer: b. O=C(COC(=O)C1CCN(S(=O)(=O)c2cccs2)CC1)Nc1ccccc1Br
