The best answer to the question: What sedimentary environments dominate the area around Vancouver, British Columbia, would be, A: Depositions of sediment carried by a braided river.

Explanation:

The geography of British Columbia is interesting because of its exposure to water, and its work in changing the landscape, and erosion. This city in Canada is blessed by two different landscapes, that are affected by their exposure to water: the Coast Mountains on the North Shore, bathed by the waters of the Straight of Georgia, and the Lowlands of the Fraser River, which encompasses most of the southern and eastern edges of the city itself. The Fraser River, particularly, has been known to have played a key role in the shaping of the landscape of Vancouver, with its braided-like shape and the triangular formation that the river takes in the city itself. This river has been elemental in the deposition of sedimentary materials, and erosion, that have transformed the landscapes of the city of Vancouver throughout time.
