The correct answer is - a. deposition.
The deltas are formed at the mouths of the rivers right before they enter a large water body, like ocean, sea, or lake. The rivers carry lot of material with them, and they do not have any problem carrying it while they are moving faster, but when they are slowing down significantly, they lose the force required to carry the material, so the material starts to deposit on the river banks. As the material deposits, it makes it hard for all of the river's water to pass through its river bed that is becoming partially blocked, so the river starts to branch out, and seen from above it takes a triangular shape if the peripheries are outlined, or as a tree that is branching out.

Continental - 2
Explanation:
The map that is presented is a climate map, meaning that it is a map that shows the climate zones in the world. The climate differs from one area to another, and the reasons for that range from latitude, wind patterns, ocean currents, exposure to sunlight, topography, water bodies, etc.
- The tropical climate types on this map are colored with green. They consist of tropical rainforests, dry tropical forests, and savanna, all being located close to the Equator.
- The dry climate types are colored pale yellowish. They are found between the tropical and modearte climates, and their main characteristics are high temperatures and very little precipitation.
- The moderate climate types are colored orange. They are located at the mid-latitudes, having relatively good amounts of precipitation and a mild climate.
- The continental climate types are colored yellow. They are located in the interior of the continents at the mid-latitudes, having high temperatures in summer and very low in winter, as well as being drier than the moderate climates.
- The polar climate types are colored with white. These climates are found around the poles. They are the coldest in the world and throughout the year the temperatures tend to be very low.
