Calcareous ooze and siliceous ooze are an example of

a) Biogenous sediment

b) Hydrogenous sediment

c) Both terrigenous sediment and biogenous sediment

d) Terrigenous sediment

Calcareous ooze and siliceous ooze are an example of Biogenous sediment.

Explanation:

Depending on the type of the  kind of material and its source , the seafloor sediments are classified. One such sea floor sediments is Biogenous sediment. This is also called as life-derived sediment. These sediments are formed form the skeletal remains of the animals and plants that lived in the past. Siliceous oozes are made up of opal  that is an amorphous, hydrated silica that forms the most skeleton of various micro-organisms where as carbonate oozes contains mostly of calcium carbonate that is present deep inside the sea.

your answer is going to be physical weathering
