Solution
The correct option is B Diatoms
Diatomaceous earth is the fossil remain of the tiny organisms knows as diatoms. It is highly absorptive and made up of silica. Cells of diatoms are surrounded by the cell wall, having a higher concentration of silica called as frustules which are composed of two overlapping halves (the epitheca and the hypotheca). Shells of diatoms are highly resistant to decomposition due to the presence of silica and are deposited in ocean beds leading to the formation of the diatomaceous earth. Thus, the correct answer is option D.
