Task: Answer the multiple choice question.
Query: Which compound exhibits a 13.018\% 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] CCCCNc1c([N+](=O)[O-])cc(C(=O)O)cc1[N+](=O)[O-]
[b] Cc1ccccc1CN1CCNC(=O)C1CC(=O)O
[c] CC(/C=C/c1ccccc1)=N\NC(N)=S
Answer: c. CC(/C=C/c1ccccc1)=N\NC(N)=S
