The correct option is D.
Because liquids flow, they can assume the shape of any container in which they are pour. Liquids are able to flow because the particles in liquid move around one another easily. When a liquid is pour inside a container, the container limit the fluidity of the liquid particles, so the liquid take up the shape of the container.<span />
Explanation:
Epipelagic zone, the topmost at the surface of the oceans receives most of the sunlight and most penetrating light rays diffuse in this layer. The temperatures at this zone, therefore, is warmer than zones below. This zone has lowest water pressure becaue there is little water column above it.
The deeper you get into the water the penetration of sunlight decreases. This is because the rays are greatly diffused even before they get to the deepest zones. The abyssalpelagic zone virtually receives no sunlight because the rays cannot get to this zone. This zone is, therefore, pitch dark and also the coldest. The deeper you get into the ocean the higher the water pressure due to the weight of the able water column. The water pressure is, therefore, highest in the abyssalpelagic zone.
