Answer: Option D.
Weathering and erosion.
Explanation:
Weathering is the broken down of rocks through the action of wind, water, air and organisms into smaller particles.
If metamorphic rock is exposed to Earth surface it will be broken down(weathering) into sediments.
When they are broken down, they can be converted to sedimentary rock when the compacted by a process called erosion.
Erosion is the washing away of the top soil or particles by the action of water or wind. When they are wash away they get compacted and form sediments.
