A Correct answer
Explanation

Playas are shallow, flat-floored desert depressions formed by the deflating action of winds, which remove fine sediments and leave behind a flat, often salt-encrusted surface. They are characteristic of arid regions where wind erosion is dominant. They are not formed by glacial, river, or marine erosion processes.
