Freezing and frozen storage of fish can give a storage life of more than one year. Provided the temperature is low enough - below -10°C bacterial action will be stopped by the freezing process. Chemical, biochemical and physical processes leading to irreversible changes will still occur, but at a very slow rate.
Therefore, the correct answer is option D.
