A) are dominated by trees and shrubs.

Swamps and marshes both are wetlands. Swamps are wetlands, which are occupied and dominated with woody trees such as mangroves and cyprus trees and shrubs whereas the marshes are not occupied with woody trees instead they exhibit reeds, grasses and sedges. The swamps are more deeper wetlands than the marshes hence, supports the growth of the trees.
