I think the best answer is B. Chinese culture influenced Japan in the areas of religion, writing, and technology. China, being in close contact with Japan even before, had many influences in Japan.

The main vent is the main outlet for the magma to escape. Secondary vents are smaller outlets through which magma escapes. The crater is created after an eruption blows the top off the volcano
B) Faulting
Layers of strata in the earths crust naturally slide along each other. Sometimes friction or blockage causes this process to stop, until enough pressure builds up to overcome whatever the resistant force is. Faulting is the process by which this pressure forces the strata to continue their movement, often producing cracks in the involved strata, and causing earthquakes and tremors in the event of an intense pressure release.
