The correct answer C. Pectinoid is the most occurring fossil that is a bivalve. They are a superfamily of marine bivalve mollusks which includes scallops and oysters. Members of this family have a triangular resilium.
Answer:
Option (C)
Explanation:
Coquina is usually defined as a sedimentary limestone rock that is found to be present in the freshwater zones and in the coastal areas. This rock is made up of broken shells that are smaller in size. The rocks can be easily broken down by the constant flowing of sea waves.
This rock is commonly formed in the same way as the other sedimentary rocks, i.e. it is formed by the deposition of sediments carrying these organic remains and eventually undergoes the process of compaction and lithification on the seafloor.
Thus, the correct answer is option (C).
The three ways in which materials respond to forces:
1.Tension,
2.Compression,
3.Bending.
Explanation:
Tension- The force that is exerted when physical objects come in contact with each other.
Compression- Compression is the application of balanced inward ("pushing") forces to different points on a material or structure.
Bending- A bending force is a force that is applied to a length of material.

There are three types of rocks:
Igneous form from the cooling and solidification of magma or lava.
Sedimentary form from pieces of other rocks.
Metamorphic form from the warping of other rocks due to heat and pressure.
