Task: Answer the multiple-choice question.
Question: Which compound has a 16.350\% 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) S=c1[nH]nc(-c2cccnc2)n1/N=C/C=C/c1ccccc1
b) O=C(O)CC(NNC(=O)c1ccccc1)C(=O)Nc1ccc([N+](=O)[O-])cc1
c) CC1CC1C(=O)OCC(=O)NNC(=O)c1ccc([N+](=O)[O-])cc1
Answer: a. S=c1[nH]nc(-c2cccnc2)n1/N=C/C=C/c1ccccc1
