The correct answer is c) point bar.
In a stream meander, the water flows faster on the outside of the bend, causing erosion and forming what is known as a cut bank. Conversely, on the inside of the bend, the water moves more slowly, which allows sediments to settle and accumulate. This accumulation forms a point bar, where deposition occurs. Essentially, point bars are the points of land that build up inside the meander and are typically composed of sand and gravel.
