The correct answer is option 1: Lysosomes. Lysosomes are known as the "suicidal bags" of the cell because they contain enzymes that can break down and digest cellular waste, debris, and even the entire cell in a process called autophagy. This is important for maintaining the overall health and functioning of the cell.

Let`s take a closer look at the other options to understand why they do not fit the description of "suicidal bags":

- Option 2: Ribosomes are responsible for protein synthesis and are not involved in cell destruction or self-destruction.

- Option 3: Dictyosomes, also known as Golgi apparatus, are involved in modifying, sorting, and packaging proteins. They are not involved in cell degradation or self-destruction.

- Option 4: Phagosomes are vesicles formed during the process of phagocytosis, where the cell engulfs and digests foreign particles or microorganisms. While phagosomes are involved in digestion, they are not responsible for the self-destruction of the cell.

Therefore, the correct answer remains option 1: Lysosomes.
