The correct answer is: C.Endoplasmic Reticulum (ER).

Explanation:

The Endoplasmic Reticulum (ER) is the primary transportation network in the cell. It is a system of membranes that moves materials (such as proteins and lipids) throughout the cell. There are two types of ER:

1.Rough ER: Studded with ribosomes, it is involved in protein synthesis and transport.

2.Smooth ER: Lacks ribosomes and is involved in the synthesis of lipids and detoxification processes.

The ER plays a key role in moving materials...
