B Correct answer
Explanation

This is the most accepted model by scientists. According to this model, the transport of cargo proteins through the Golgi complex occurs by the progression of cisternae from the cis face to the trans face of the Golgi stack. Each cisterna changes its position in the stack repeatedly until it reaches the trans face. Thus, the cisternae themselves act as carriers in this intra-Golgi trafficking segment.
