Problem statement: Answer the multiple choice question.
Question: Which drug has a -26.502\% 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=[N+]([O-])c1cccnc1NCCc1c[nH]c2ccccc12
b CSc1ccc(CNc2ncc(-c3cccc([N+](=O)[O-])c3)n2C)cc1.O=C(O)C(=O)O
Answer: b. CSc1ccc(CNc2ncc(-c3cccc([N+](=O)[O-])c3)n2C)cc1.O=C(O)C(=O)O
