Answer; 
a.) the most common kind of cell division 
c.)same number of chromosomes in each daughter cell as in the parent cell.
Explanation; 
-Mitosis is a type of cell division which takes place ins the body cells or the somatic body cells, where the parent cell divides to give two daughter cells that have the same number of chromosomes as the parent. Thus, if the parent cell will be diploid (2n) then the daughter cells will also be diploid (two sets of each chromosome).
-This type of cell division plays an important part in the development of embryos, and it is important for the growth and development of human bodies as well.
