Task: Answer the multiple choice question.
Question: Which drug has a 19.517% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: COC(=O)C1=C(c2cc3ccccc3s2)C[C@@H]2CC[C@H]1N2C(=O)NCCO
b: Cc1ccc(S(=O)(=O)N2CCOCC2)cc1NC(=O)CSc1n[nH]c(N)n1
c: O=[N+]([O-])c1cccc(-c2ccc(/C=N/NC(=S)Nc3ccccc3)o2)c1
d: O=C(O)c1cccc(Nc2c([N+](=O)[O-])cc([N+](=O)[O-])c3cccnc23)c1
Answer: c. O=[N+]([O-])c1cccc(-c2ccc(/C=N/NC(=S)Nc3ccccc3)o2)c1
