Answer: Option D
<u>Explanation:</u>
Recycling can be done through open and closed loop processes. In open loop processes, the original material is not recycled indefinitely and is excluded from the loop and ultimately becomes a waste and degradation.
Where as in the closed loop process, the recycling of the material can be done indefinitely and can be used in the utilization loop which means that there is less of wastage. The closed loop process is more sustainable.
There are two main forms of return migration: voluntary return and forced return. Data on forced return are usually collected by national and international statistical offices, border protection and immigration law enforcement agencies.

Answer:
Option (A)
Explanation:
The cretaceous period formed the last period of the Mesozoic era, marked by the occurrence of some distinct major events, and it began about 145 million years ago and ended by about 65 million years ago. The name Cretaceous is actually derived from the Latin word 'Creta' which means “chalk”. Chalk usually refers to the white colored, soft, powdery limestone rock that is primarily comprised of fossil shells. These are basically dominated by the calcite minerals.
By the end of this period, the dinosaurs were completely wiped out from the earth and the flowering plants started to evolve after the mass extinction event, which is commonly known as the Cretaceous-Tertiary boundary (K-T boundary).
Thus, the name Cretaceous was given because during this time period, there was abundant deposition of marine limestones (chalk), depicting that the sea level was comparatively higher than the present day.
Hence, the correct answer is option (A).
