Task: Answer the multiple-choice question.
Query: Which drug exhibits a 2.910\% 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 additional words.
Options:
a O=C(NNc1cccc([N+](=O)[O-])c1)/C(=C\c1cccnc1)NC(=O)c1ccccc1
b CCCCN(C(=O)c1cccc(-n2cnnn2)c1)c1c(N)n(CC(C)C)c(=O)[nH]c1=O
Answer: b. CCCCN(C(=O)c1cccc(-n2cnnn2)c1)c1c(N)n(CC(C)C)c(=O)[nH]c1=O
