The option B is correct.
Desert pavement is created as a result of deflation.
Further Explanation:
Desert pavement: It refers to surface of desert that is covered with firmly packed interlocking rounded or angular fragments of rock. It is caused by removal of dust, sand, and other finely grained materials by the wind and occasional rain.
Justification for the correct and incorrect answer:
A.
Abrasion: This option is incorrect.
It is the process of erosion in which friction caused by scratching, scuffing, marring, wearing down, and rubbing wears away surface over time. So, it does not cause the desert pavement.
B.
Deflation: This option is correct.
It is erosion caused by wind of loose material from dry areas of sediments. It occurs in dry lake beds, deserts, glacial outwash plains and floodplains. So, the reason for desert pavement is deflation.
C.
Blowouts: This option is incorrect.
It does not cause the desert pavement because these are depressions of sand found in a psammosere caused the due to the removal of sediments by wind.
D.
Water erosion: This option is incorrect.
It refer to breakdown of the rocks into tiny particles and their removal by water. There are two types of water erosion namely, gully and rill erosion. So, water erosion does not cause the desert pavement.
Therefore, the desert pavement is created as a result of deflation.
