Answer:
B) MBO
Explanation:
An MBO is a secondary vocational education program carried out in the Netherlands. It lasts for four years and its courses go from assistant training, basic vocational training, professional training and finally middle-management training. It is basically the dutch equivalent of technical college, since you start the MBO when you are around 18 years old. After you complete your MBO you can continue your college education.
The MBO covers a lot of professions but it is basically hands on training, since between 20 -60% of the time is practical training (they work as someone else's assistant or trainee).
