Task: Answer the multiple-choice question.
Question: Which compound has a 19.516% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
[a] O=C(CSc1n[nH]c(-c2cccnc2)n1)Nc1ccccc1[N+](=O)[O-]
[b] NC(=O)C1CCN(C(=O)c2ccc(NC3=NC4CS(=O)(=O)CC4S3)cc2)CC1
[c] O=C(O)c1ccc2c(c1)C(=O)N(c1ccc([N+](=O)[O-])cn1)C2=O
Answer: c. O=C(O)c1ccc2c(c1)C(=O)N(c1ccc([N+](=O)[O-])cn1)C2=O
