Task: Answer the multiple choice question.
Query: Which drug exhibits a -0.620\% 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) O=C(Nc1cccc2c1CCCC2)c1cc([N+](=O)[O-])ccc1Cl
b) CCCC[C@@H]1CNC(=O)C(=O)N1CCCc1cc(OC)c(OC)c(OC)c1
Answer: a. O=C(Nc1cccc2c1CCCC2)c1cc([N+](=O)[O-])ccc1Cl
