Task: Answer the multiple-choice question.
Query: Which compound has a -1.000\% 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.) O=S(=O)(N/N=C/c1ccc2c(c1)OCO2)c1ccc(Br)cc1
b.) COc1ccc(CCNC(=O)c2sc3ccccc3c2Cl)cc1OC
c.) O=C(Nc1ccncc1[N+](=O)[O-])c1ccc([N+](=O)[O-])cc1[N+](=O)[O-]
Answer: c. O=C(Nc1ccncc1[N+](=O)[O-])c1ccc([N+](=O)[O-])cc1[N+](=O)[O-]
