The Ottoman Army Carried All Wages, Gunpowder, Weapons, and the Majority

The Ottoman army carried all wages, gunpowder, weapons, and the majority of its food in its wagons and barges because:

A) The sultan feared that the converted Christian Janissaries would revert to their own religion.
B) The soldiers did not know how gunpowder worked, and they needed experts in the baggage train.
C) The force was rendered smaller and more mobile as a result of these precautions.
D) Soldiers were not permitted to provision themselves from the belongings of villagers.
