D : the number of generations in one population
Option A
This option represents only chloroplast which is a cell organelle.
Option B
This option only talk about cell division.
Option C
This option is related to cellular respiration which is carried out in mitochondria.
Option D
It tells us that different tissues are connected like bone connect with muscle cells.
Conclusion
The correct option is D which provide the best evidence for the idea that multi cellular organisms are composed of organized arrangements of differentiated cells.

Answer:
D. LINE-promoted transposition.
Explanation:
Pseudogenes are traditionally defined as sequences that closely resemble known genes but do not produce a functional protein, which in many cases were actually genes, or copies of genes, degenerated by mutational processes that alter the reading frame of coding regions (ie that encode the amino acid sequence) or that interfered with the promoter elements that controlled their expression.
Pseudogenes originate by the same mechanisms as protein coding genes, followed by the subsequent accumulation of disabling mutations (e.g., insertions, nucleotide deletions, and / or substitutions) that disrupt the reading sequence in the coding regions, or lead to the insertion of a premature termination codon or the aforementioned reading frame change. However, it is believed that the transposition promoted by LINE is the main transposition responsible for the appearance of pseudogenes.
There are four types of plate boundaries:
Divergent boundaries -- where new crust is generated as the plates pull away from each other.
Convergent boundaries -- where crust is destroyed as one plate dives under another.
Transform boundaries -- where crust is neither produced nor destroyed as the plates slide horizontally past each other.
Plate boundary zones -- broad belts in which boundaries are not well defined and the effects of plate interaction are unclear.
