Task: Answer the multiple-choice question.
Query: Which drug exhibits a 19.324% 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: Cc1c(NC(=O)Nc2ccccc2[N+](=O)[O-])c(=O)n(-c2ccccc2)n1C
b: CCOC(=O)c1nn(-c2cccc(C)c2)c2nnc(Cc3ccc(C)cc3)c(=O)n12
Answer: a. Cc1c(NC(=O)Nc2ccccc2[N+](=O)[O-])c(=O)n(-c2ccccc2)n1C
