Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -4.610% 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(CSc1ccsc1[N+](=O)[O-])N1CCCCC1
b: CC(=O)Nc1ccc(NC(=O)C(C)OC(=O)CCc2nc3ccccc3s2)cc1
Answer: a. O=C(CSc1ccsc1[N+](=O)[O-])N1CCCCC1
