It would be A. Commensalism because only the plant is being benefitted in this relationship, whilst there is no harm nor benefits done to the fungus.
The features which create deposition from rivers are found in food plains, alluvial fan, and deltas.
Deposition is termed as a process whereby the transported materials by a river are being deposited.
When a river losses energy we say that there is deposition.
Where there is high flow of water in a river deposition is likely to occur because more sediments are being carried as well as erosion which is being caused.
Skin remains red after a bad sun burn because:
inflammation causes increased blood flow.
Explanation:
When our skin is exposed to sun rays , the epidermal layer starts getting damaged. The damage to the cell caused by sun rays triggers the melanin secretion. Increased secretion of melanin results in darkening of the exposed region .
However, the damage and inflammation to the skin increases blood flow to the skin, this causes reddening of the skin.

The stabilization of a radioactive parent element into a stable daughter element occurs through the process of radioactive decay. The unstable atomic parent emits radiation and loses its energy. This leads to the formation of a daughter element, which is less radioactive or is stable.
