Hint: Mitosis is also known as equational division. It occurs in 4 stages usually that is prophase, metaphase, anaphase and telophase. At the end of mitosis the number of chromosomes remains the same as before the division so it is called an equational division of growth.

Complete answer:
In animals the equational division that is mitosis usually occurs in the meristematic cells. The cells which are in the state of active division are known as meristematic cells. Mitosis was first observed by Strasburger in a plant cell and Walter Flemming in an animal cell.
Now let us know which of them are in the state of active cell division.
Leaf tip :- the tip of the leaf does not contain actively dividing cells. They are devoid of meristematic tissue. They have become special and structure and function. So they are not good to study mitosis .
Shoot tip :- the shoot tip consists of shoot apical meristem. They are in the state of active cell division but they do not take stains of the colour. So they are not clearly visible under the microscope.
(С) Root tip :- the root tip consists of root apical meristem. They are in a state of active cell division as they have meristematic tissue. They take stain completely when stained and they are clearly visible under microscope so this is the best material to study mitosis.
(D) Gamete :- Mitosis occurs in the somatic cells of the animals. It also occurs in the gonads for multiplication of germ cells But this material is not good to study mitosis as it is not clearly visible under the microscope as it is not clearly visible under the microscope.

Our required option is C) root tip.

Note: Mitosis is a process in which a parent cell divides into two identical daughter cells. These cells are identical to each other as well as to the parent cell. It is a type of division in which already duplicate chromosomes are distributed into two daughter cells equally.
