Task: Answer the MCQ question.
Query: Which drug exhibits a 1.125\% 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) CC1=CCC2([N+](=O)[O-])CN(CC(=O)O)CC1([N+](=O)[O-])C2
b) COC(=O)C1=C(C)OC(N)=C(C#N)C1c1ccccc1F
c) Cc1cccc(CC2CC(=O)N(c3ccc([N+](=O)[O-])cc3)C2=O)c1
Answer: b. COC(=O)C1=C(C)OC(N)=C(C#N)C1c1ccccc1F
