The correct answer is: D.Weathering of rocks.

Phosphate (PO₄) moves from rocks to sediments through the process of weathering. Over time, rocks containing phosphate minerals (like apatite) break down due to physical or chemical weathering, releasing phosphate ions into the soil and water. These ions can then be transported by water (runoff) to form sediments in rivers, lakes, and oceans.
