Explanation:

• Delta formation is a complex geological and geomorphological process that occurs at the mouths of rivers and is influenced by various environmental and geological conditions. The primary conditions favoring delta formation include: o High Sediment Load: Deltas typically form in areas where rivers carry a significant amount of sediment, such as sand, silt, and clay. High sediment loads are crucial because they provide the material needed to build up the delta over time. o Low Wave Energy: Deltas are more likely to form in regions with relatively calm and sheltered coastal conditions, where wave energy is minimal. High wave energy can disperse sediment before it has a chance to accumulate and form a delta. ü Turbulent waves can disrupt the formation and maintenance of deltas by redistributing sediment. o Shallow Coastal Waters: Deltas tend to develop in shallow coastal areas or continental shelves. Shallow water allows sediment to settle out of the river's flow and accumulate on the seabed. o Minimal Tidal Influence: Strong tidal currents can disrupt the formation and maintenance of deltas by redistributing sediment. Therefore, areas with minimal tidal influence are more conducive to delta formation. o Stable Sea Level: Stable sea levels or slow rates of sea-level rise are important for delta formation. Rapid sea-level rise can submerge newly formed deltas, hindering their growth. o Sufficient Freshwater Flow: Deltas thrive on a consistent supply of freshwater from rivers. Seasonal variations in flow can influence delta growth, with higher flows typically leading to more rapid deposition. o Multiple Distributaries: Deltas often have multiple distributary channels through which river water and sediment can flow into the sea. These distributaries help distribute sediment across a wider area. • Hence option (c) is the correct answer.
