Task: Answer the multiple choice question.
Query: Which drug exhibits a -2.385\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a.) CC1(C)CC(N2CCOCC2)=CC(=[N+]2CCOCC2)C1.[I-]
b.) CCN(CC(=O)NC1CCS(=O)(=O)C1)c1ccc(S(C)(=O)=O)cc1[N+](=O)[O-]
Answer: b. CCN(CC(=O)NC1CCS(=O)(=O)C1)c1ccc(S(C)(=O)=O)cc1[N+](=O)[O-]
