Task: Answer the multiple choice question.
Question: Which drug exhibits a -0.527\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.

b.) Cc1ccccc1Cn1c([N+](=O)[O-])cnc1C
c.) CCOP(=O)(OCC)C(C)(C)NC(=O)c1cc([N+](=O)[O-])cc([N+](=O)[O-])c1
d.) Cc1ccc(C(=O)NCc2ccccc2CN2CCCC2)cc1S(=O)(=O)N1CCOCC1
e.) Cc1ccc(-n2c(C)c(C)c3c(N)ncnc32)cc1
Answer: b. Cc1ccccc1Cn1c([N+](=O)[O-])cnc1C
