The most characteristic feature of clastic  sedimentary rocks is "stratification".
<u>Answer:</u> Option A
<u>Explanation:</u>
"Stratification" is an essential characteristic of the sedimentary rocks take place in an igneous rock produced at the surface of the Earth naturally due to volcanic fragmental deposits and flows of lava. It defines the pattern in which sediment layers are layered over each other and may occur on a scale of hundreds of meters, even down to sub-millimeter. 
It also results from variations in texture or composition during deposition. Delays in deposition may also permit for variations to the older deposits before coverage given by new sediments. This mechanism in sedimentary rocks change in both, the degree of prominence and in structure details.

When the continents separated, organisms were forced to be placed in different locations with different environmental conditions. In order to survive in their new environment, over time, various flora and fauna developed various body mechanisms to cope up. This brought up the speciation of flora and fauna.

Active transport;
The movement of particles would be most affected by a disorder that causes damage to carrier proteins is the active transport.
Explanation;
Active transport involves the movement of materials against the concentration gradient.
This type of transport requires energy in form of ATP to aid the movement of particles from a lower concentration to a higher concentration.
Active transport requires carrier proteins such as the sodium-Potassium pump, to move materials in and out of the cell.
