Task: Answer the multiple choice question.
Query: Which drug exhibits a 0.973\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
[a] CCOC(=O)C/C(C)=N\Nc1ccc([N+](=O)[O-])cc1[N+](=O)[O-]
[b] CCCC(=O)Nc1ccc(-c2cn3cccnc3n2)cc1
[c] Cn1c(=O)oc2cc(S(=O)(=O)NC3CCN(Cc4ccccc4)CC3)ccc21
Answer: a. CCOC(=O)C/C(C)=N\Nc1ccc([N+](=O)[O-])cc1[N+](=O)[O-]
