Final answer:
Cementation is the agent of lithification, the process of transforming clastic sediments into rocks by the precipitation of mineral matter in their pore spaces. Water is squeezed out during compaction and minerals act as a glue, holding the sediment together. option d is answer
Step-by-step explanation:
Cementation is the agent of lithification, the process of transforming clastic sediments into rocks by the precipitation of mineral matter in their pore spaces. During compaction, water is squeezed out and minerals act as a glue, holding the sediment together. Common minerals involved in cementation include calcite, quartz, and pyrite.
