Problem statement: Answer the multiple choice question.
Question: Which compound has a 1.305\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: COc1ccc(OC)c(C2=C[N+](=O)C(C)(C)C(C)(C)N2[O-])c1
b: COc1cccc(NC(=O)CN2C(=O)C3(OCCCO3)c3ccccc32)c1
c: CN(c1ccccc1)S(=O)(=O)c1cccc(NC(=O)CN2C(=O)NC3(CCCCC3)C2=O)c1
Answer: a. COc1ccc(OC)c(C2=C[N+](=O)C(C)(C)C(C)(C)N2[O-])c1
