Sediment can be carried by 1- wind only 2-water 3-water or ice only 4- wind, water or ice

I'd say option 4, because all of those are capable of changing the enviroment

Sediments can be deposited by wind, water or ice. The appropriate answer is 4/ D. Sediments are materials deposited at the Earth's surface by physical agents (wind, water or ice), chemical agents (precipitation from oceans lakes and rivers) or biological agents ( organisms living or dead).

Sediments deposited by wind are called eolian sediments. Sediments deposited in the open ocean are called pelagic sediments. They are composed of fine grained terrigenous and biochemically precipitated particles.
Sediments deposited by ice are called moraine sediments.
