Task: Answer the MCQ question.
Query: Which drug has a 2.105\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: C/C(=N\Nc1ccc([N+](=O)[O-])cc1)c1ccc2c(c1)OCO2
b: O=C(Nc1ccc2ccccc2c1)c1ccc(Cl)cc1Cl
c: O=C(COc1ccc(/C=C\[N+](=O)[O-])cc1)N1CCOCC1
Answer: a. C/C(=N\Nc1ccc([N+](=O)[O-])cc1)c1ccc2c(c1)OCO2
