Final answer:
The ER-Golgi intermediate compartment (ERGIC) is a membrane-bound organelle that serves as a transitional area between the ER and the Golgi apparatus for the sorting and transport of proteins and lipids. The correct option is B.
Step-by-step explanation:
The ER-Golgi intermediate compartment (ERGIC) is a key component of the cellular secretory pathway, acting as a transition zone between the endoplasmic reticulum (ER) and the Golgi apparatus.
Specifically, the ERGIC functions as a membrane-bound organelle where proteins and lipids from the ER are sorted and transported to the Golgi apparatus. It is neither a transport vesicle, cytosolic enzyme, nor a ribosomal complex. Thus, the correct answer to the question is B) A Membrane-Bound Organelle.
