Task: Answer the multiple choice question.
Question: Which drug exhibits a 0.453\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: Cc1cccc(Nc2nc(NCC3CCCO3)nc(N)c2[N+](=O)[O-])c1
b: CC(C)c1ccc(NC(=S)NNC(=O)c2cccnc2)cc1
Answer: a. Cc1cccc(Nc2nc(NCC3CCCO3)nc(N)c2[N+](=O)[O-])c1
