The answer is B. Divergent plate boundary.
Let's look into the choices one by one:
A. Subduction-This is false.
Under subduction force, the subduction plate boundary cause two plates to collide, and thee denser oceanic plate will subduct under the less dense continental plate, causing the plate to be melted in the mantle. As the plate boundary destroy the plate instead of creating new materials, this is false.
B. Divergent-This is correct.
Under the rising convection current of magma, the plates move apart from each other causing crack. The uprising magma would then fill the crack and cools down to form new plate material which adds to the lithosphere.
C. Collisional -This is false.
Collisional and Subduction plate boundary is actually the same,where the plates collide.As mentioned, this does not adds to the lithosphere.
D. Transform- This is false.
Transform plate boundary is where the plates slide past each other and no material is created or destroyed.
Therefore, the answer is B. Divergent plate boundary.

Answer:
The global winds are Prevailing winds, Trade winds, Polar winds 
Explanation:
The large global system is created by uneven heating of the earth's surface from above and below the surface. The pressure is measured from the sea level. The large scale motion of air along with oceanic circulation is derived from thermal energy induced by the geomorphic agent and the sun's potential energy. Movement of these pressure belts from north to south is in the form of cells that are fundamental to the rotation of the earth's heating and cooling. On the basis of altitudinal variations, various latitudinal winds/ cells are formed like the Hadley, Polar and Ferrel cell. The ITCZ divides these into northern and southern parts. The equator is the origin of hadley cell and tradewinds and in mid latitudes from 30 to 60 degrees comes the Westerlies.  And from 60 to 90 degrees the polar cells in northand south. The ITCZ is the region of mixing.
