Task: Answer the MCQ question.
Question: Which drug exhibits a 12.086% 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] O=C(NNC(=O)c1ccccc1[N+](=O)[O-])Nc1ccc(Cl)cc1
[b] Clc1cc2c(cc1/C=N/Nc1nc(N3CCOCC3)nc(N3CCOCC3)n1)OCO2
[c] CCOCCOc1nc2c(c(=O)n(C)c(=O)n2C)n1Cc1ccc(C)cc1
Answer: a. O=C(NNC(=O)c1ccccc1[N+](=O)[O-])Nc1ccc(Cl)cc1
