Golgi Apparatus because it has the function of storage modification and packing of reproducts.

The correct answer is option 'C': Golgi apparatus.

The Golgi apparatus is an organelle found in eukaryotic cells and is responsible for the sorting, processing, and packaging of proteins and lipids. It plays a crucial role in cell secretion, which is the process by which cells release substances into their external environment.

Here is a detailed explanation of how the Golgi apparatus is associated with cell secretion:

1. Structure of the Golgi Apparatus:
- The Golgi apparatus is composed of a series of stacked membrane-bound sacs called cisternae.
- It is located near the nucleus and is interconnected with the endoplasmic reticulum (ER).

2. Formation of Secretory Vesicles:
- Proteins and lipids synthesized in the ER are transported to the Golgi apparatus.
- As these molecules enter the Golgi, they undergo various modifications, such as glycosylation and phosphorylation.
- The Golgi apparatus acts as a processing center, modifying and sorting these molecules.

3. Sorting and Packaging of Molecules:
- Within the Golgi apparatus, proteins and lipids are sorted based on their final destination.
- Different enzymes present in the Golgi modify these molecules, adding specific tags or signals that determine their ultimate location.
- Proteins destined for secretion are packaged into secretory vesicles, which bud off from the Golgi apparatus.

4. Maturation and Secretion:
- Secretory vesicles move towards the plasma membrane, where they fuse and release their contents to the external environment.
- This process is called exocytosis, and it allows cells to secrete various substances like hormones, enzymes, and antibodies.
- The Golgi apparatus also plays a role in the maturation of lysosomes, which are organelles involved in the breakdown of cellular waste and foreign substances.

In summary, the Golgi apparatus is associated with cell secretion as it processes, sorts, and packages proteins and lipids for secretion. It plays a vital role in the formation of secretory vesicles and is responsible for the maturation of lysosomes.
