Task: Answer the multiple-choice question.
Question: Which drug exhibits a 2.466\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: CC1=C(C(=O)Nc2ccc(C)cc2C)C(c2cccc([N+](=O)[O-])c2)n2nc(C(=O)OC(C)C)nc2N1
b: CC(C)(C)c1cccc(P(=O)(c2ccccc2)c2ccccc2)c1O
c: Cc1n[nH]c(C)c1Sc1ccc([N+](=O)[O-])cc1
Answer: a. CC1=C(C(=O)Nc2ccc(C)cc2C)C(c2cccc([N+](=O)[O-])c2)n2nc(C(=O)OC(C)C)nc2N1
