The diagram shows a geographic feature. Based on the diagram, structure X is
A
a delta that is changing due to sediment deposits from ocean currents.
B
an island that is changing due to the movement of plate boundaries.
с
a delta that is changing due to sediment deposits from a river.
D
an island that is changing due to increasing volcanic lava flow.

C

because b and d are wrong, and a is also wrong because sediments usually come from the river not an ocean
