Answer:
Option (1)
Step-by-step explanation:
Sediments are defined as broken materials such as rock fragments, soil particles, that are transported from one place to another by the agents such as wind, water and ice. The sediments are formed from the weathering of rock bodies.
The source of a sediment refers to the point (location) from which the sediments are originated.
The fragments of other rocks can be considered to be a source of sediment because these are broken fragments were initially a part of another rock, that eventually weathered, and eroded and deposited at a different place.
hence, the correct answer is option (1).
