Pollen grains are produced by meiosis of microspore mother cells. Diploid (2n) microspore mother cells are housed in the anther and divide by meiosis to form four haploid (n) microspores. Each microspore develops by mitosis into a pollen grain. So pollen grains are haploid and when cultured it produces a haploid plant. Another wall has four wall epidermis, endothecium, middle layers and tapetum and all of them are diploid and produce diploid plants when cultured on artificial media. So, the correct answer is option C.

On culturing the young anther of a plant a botanist got a few diploid...
Explanation:
Culturing the young anther of a plant involves the process of anther culture, where the anther is excised and placed on a nutrient medium to promote the growth of plant cells. This technique is used to produce haploid plants, which can then be utilized in plant breeding programs.
During anther culture, it is possible to obtain both diploid and haploid plants. The diploid plants are likely to arise from the cells of the anther wall, also known as the somatic cells.
Reasoning:
The anther wall consists of somatic cells, which are diploid cells. These cells undergo the process of mitosis to produce diploid cells during anther culture. On the other hand, the pollen grains, which contain the generative cell and the vegetative cell, are haploid cells.
The generative cell of the pollen is involved in the process of fertilization and gives rise to the male gametes. It is a haploid cell and therefore cannot give rise to diploid plants.
The vegetative cell of the pollen is responsible for the growth and development of the pollen tube during pollination. It is also a haploid cell and cannot give rise to diploid plants.
Conclusion:
Based on the above reasoning, it can be concluded that the diploid plants obtained during anther culture are likely to arise from the cells of the anther wall. These diploid plants can be further utilized in plant breeding programs to introduce desirable traits into crop plants.
