Problem statement: Answer the multiple choice question.
Query: Which drug has a 13.520\% 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 O=C(O)c1ccc(Nc2ncc([N+](=O)[O-])cc2[N+](=O)[O-])cc1
b COc1ccc(CC/C(C)=N\NC(N)=O)cc1
c O=C(C1COc2ccccc2O1)N1CCN(S(=O)(=O)c2ccccc2)CC1
Answer: a. O=C(O)c1ccc(Nc2ncc([N+](=O)[O-])cc2[N+](=O)[O-])cc1
