Metamorphic rocks are produced when rocks are recrystallized by heat and pressure.
Although they began as a different kind of rock, metamorphic rocks have undergone significant alteration from their igneous, sedimentary, or previous metamorphic forms. When rocks are exposed to extreme temperatures, high pressures, hot mineral-rich fluids, or, more frequently, some combination of these conditions, metamorphic rocks are created.
High pressures and temperatures both have a role in recrystallization. Solid crystals can reorganize themselves by migrating as a result of high temperatures. The crystals within the rock at their places of contact dissolve under high pressure.

The correct answer is - A. They invaded Manchuria.
In the first half of the 20th century, Japan was changing drastically, the country began to militarize intensely, and it also became very hungry for new territories.
