Task: Answer the multiple choice question.
Question: Which compound exhibits a -29.956% 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.) O=C(NC(=S)N1CCN(c2ccc(Cl)cc2[N+](=O)[O-])CC1)c1cccs1
b.) O=C1CC(c2ccccc2)CC(O)=C1C=NCc1ccc(Cl)cc1
Answer: a. O=C(NC(=S)N1CCN(c2ccc(Cl)cc2[N+](=O)[O-])CC1)c1cccs1
