Task: Answer the MCQ question.
Question: Which drug has a -13.393\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: C[n+]1nn(CC(=O)c2ccccc2)c2ccccc21.[Br-]
b: COc1cc(NC(=O)CN2C(=O)NC(C)(c3ccc4ccccc4c3)C2=O)c(C)cc1[N+](=O)[O-]
c: O=C(CC(c1ccccc1)c1ccccc1)NCC(O)c1ccc([N+](=O)[O-])cc1
d: O=C(CNC(=O)c1ccc2ccccc2c1)OCC(=O)N1CCN(S(=O)(=O)c2ccc3ccccc3c2)CC1
Answer: c. O=C(CC(c1ccccc1)c1ccccc1)NCC(O)c1ccc([N+](=O)[O-])cc1
