Problem statement: Answer the multiple-choice question.
Query: Which compound exhibits a 1.432\% human ether-à-go-go related gene (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] O=C(NCc1ccco1)C(c1ccncc1)N(CCC1=CCCCC1)C(=O)Cn1nnc2ccccc21
[b] NS(=O)(=O)c1ccc(CNC(=O)c2cc(-c3cccnc3)nc3ccccc23)cc1
[c] COc1cc(CC(=O)O)c([N+](=O)[O-])cc1OC
Answer: c. COc1cc(CC(=O)O)c([N+](=O)[O-])cc1OC
