23. Which of the following species is most likely to become extinct? A. a species that is well adapted to its environment
B. a species that is losing its habitat due to deforestation
C. a species that has a great amount of genetic variation
D. a species that has a decreasing number of predators

B. Is the answer. They are losing their habitat and therefore will be more likely to go extinct

The correct option is clastic

Clastic sedimentary rocks are made up of small pieces known as clasts of pre existing rocks. These pieces of rocks are loosened by weathering process and then moved to some basin or depression where sediment is placed. If the sediment is buried deeply under ground, it becomes hard, compacted and cemented which results in the formation of sedimentary rock.
