Task: Answer the multiple-choice question.
Question: Which drug exhibits a 12.293\% 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 CN(C)C(=O)Oc1ccc2c(c1)O/C(=C\c1cccc([N+](=O)[O-])c1)C2=O
b CC(C)CC1Nc2ncnc(N3CCN(c4ccccc4)CC3)c2N(Cc2ccccc2)C1=O.O=C(O)C(F)(F)F
c CCOc1ncc(S(=O)(=O)N2CCN(CC)CC2)cc1C(=O)O
Answer: a. CN(C)C(=O)Oc1ccc2c(c1)O/C(=C\c1cccc([N+](=O)[O-])c1)C2=O
