Task: Answer the multiple choice question.
Question: Which drug exhibits a 19.299% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a. COc1cc(NS(=O)(=O)c2ccc(NC(=S)NC(=O)CC(C)C)cc2)nc(OC)n1
b. Cc1ccnc2nc(C(=O)OCC(=O)N(CC(C)C)CC(C)C)nn12
c. N/C(=N/OC(=O)c1cccc([N+](=O)[O-])c1)c1cccc([N+](=O)[O-])c1
Answer: c. N/C(=N/OC(=O)c1cccc([N+](=O)[O-])c1)c1cccc([N+](=O)[O-])c1
