*Answer*: C.Bone marrow
*Explanation*: In the human adult, the bone marrow produces all of the red blood cells, 60–70 percent of the white cells (i.e., the granulocytes), and all of the platelets.
Why the answer not A,B&D:
The lymphatic tissues, particularly the thymus, the spleen, and the lymph nodes, produce the lymphocytes (comprising 20–30 percent of the white cells). The reticuloendothelial tissues of the spleen, liver, lymph nodes, and other organs produce the monocytes (4–8 percent of the white cells). The platelets, which are small cellular fragments rather than complete cells, are formed from bits of the cytoplasm of the giant cells (megakaryocytes) of the bone marrow.

Answer:
A. Some speculate that they were blown out to the islands by a massive storm
Explanation:
The common rosefinches are thought to have arrived on the Hawaii islands between 6 and 7 million years ago. As the common rosefinches are not big birds and they can not fly over very long distances, the scientists believe that it is a massive storm that blow some individuals to the Hawaii islands. This is nothing weird, as it has been witnessed numerous times how massive storms manage to carry some smaller birds to places where they are not able to fly on their own. Once there, the birds encountered suitable conditions for living and lot of open niches in the food chain. This resulted in quick diversification of the common rosefinches, with members of the species gradually adapting to a particular niche, experiencing changes to be more competent, and creating numerous new species after some time.
