Jet streams are associated with fronts because of the:

B)reduced friction above the front.
C)large temperature gradient.
D)clouds forming there.

Jet streams are fast moving air currents that are concentrated in a narrow band in the upper atmosphere. These currents are primarily caused by differences in atmospheric temperature, and therefore, are associated with fronts that have a large temperature gradient. This temperature gradient is what causes the jet stream to form and move, which is why it is often referred to as a "frontal boundary." The other options, such as higher pressure, reduced friction, and cloud formation, can also play a role in the formation or behavior of jet streams but are not directly associated with fronts.
