Correct option is D
The correct answer is: (d), Arcuate Delta
Arcuate delta: This type of delta results when light deposition gave rise to shallow, shifting distributaries and a general fan shaped profile.
Example: Nile, Ganga, Indus

Bird foot Delta: This type of delta emerges when limestone sediment deposits do not allow downward seepage of water. The distributaries seem to be flowing over projection of these deposits which appear as a bird’s foot.
Example: Mississippi river
Estuarine Delta: Estuarine deltas form at the mouth of rivers where freshwater mixes with saltwater from the ocean or sea, resulting in brackish water environments. These deltas often have a funnel-like shape and are influenced by tidal currents.
Example: Tapi, Narmada, Hudson, Mackenzie
Cuspate Delta: Cuspate deltas have triangular shapes with pointed protrusions extending into the sea. They typically form in areas with low sediment supply and strong wave action, leading to the formation of triangular-shaped landforms.
Example: Tiber river on the west coast of Italy.
