Task: Answer the MCQ question.
Query: Which drug has a 9.175\% 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 other words.
Options:
a) CN=Cc1nc(-c2ccccc2)oc1O
b) Nc1nn(-c2ccccc2)nc1C(=O)OCc1ccccc1F
c) CN1C2=CC=CC=CC2=[N+](C)C12C([N+](=O)[O-])=CC([N+](=O)[O-])=CC2=[N+]([O-])[O-]
d) O=C(c1cc(-c2ccc(O)cc2)on1)N1CCCc2ccccc21
e) CC(=O)c1ccc(S(=O)(=O)N2CCc3ccccc3C2)cc1
Answer: c. CN1C2=CC=CC=CC2=[N+](C)C12C([N+](=O)[O-])=CC([N+](=O)[O-])=CC2=[N+]([O-])[O-]
