Task: Answer the multiple choice question.
Query: Which drug exhibits a 5.123\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
[a] Cc1ccc(/C=N/NC(=O)c2nnn(-c3nonc3N)c2CN(C)c2ccccc2)s1
[b] CCCCOc1ccc(C(=O)Nc2ccc(C)cc2[N+](=O)[O-])cc1
Answer: b. CCCCOc1ccc(C(=O)Nc2ccc(C)cc2[N+](=O)[O-])cc1
