Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 11.893\% 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 CNc1nc(N)c([N+](=O)[O-])c(NC2CCCCC2)n1
b Cc1ccc(C(C)C)c(OCCN2C(=O)NC(C)(C)C2=O)c1
Answer: a. CNc1nc(N)c([N+](=O)[O-])c(NC2CCCCC2)n1
