What event found at a transform boundary will form metamorphic

When two plates moves slide passing one another, then it is known as the transform plate boundary.

During this transform plate movement, the plates experiences friction and shearing, accompanied by compressive stress, thereby increases the transfer of heat. Due to this, the rocks in those region undergoes metamorphism process because of the high temperature and pressure condition.

Therefore, metamorphic rocks are formed due to this events at the transform plate boundary.

the supermassive black hole is in the middle of the galaxy.

c is the correct answer!
