Answer:

The correct answer would be A. Fragments of rock are squeezed and cemented together.

Clastic sedimentary rocks refer to the group of rocks formed by clasts or pieces of pre-existing rocks.

Four basic steps are involved in the formation of clastic sedimentary rocks:

Weathering: it causes the loosening of the rocks.
Transportation: sediment is carried along the currents to the depression or basin.
Deposition: sediments are deposited and trapped in the basin.
Compaction: sediments are compacted and cemented together and form a rock.
