Task: Answer the multiple-choice question.
Question: Which drug exhibits a 13.104\% 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] CCc1nnc(NS(=O)(=O)c2ccc(NC(=O)c3cccc([N+](=O)[O-])c3)cc2)s1
[b] COc1cc(SC#N)ccc1N=Cc1c(C)[nH]n(-c2ccc(C)c(C)c2)c1=O
Answer: a. CCc1nnc(NS(=O)(=O)c2ccc(NC(=O)c3cccc([N+](=O)[O-])c3)cc2)s1
