Hint:
The plant hormone which plays a role in the growth, development and physiology of the plant. It has some other functions like stimulation of cell division.
Complete answer:
You can answer this question by looking at each option carefully one-by-one. If we look at the option A i.e., Insulin. Insulin is a hormone which is produced by pancreas which is responsible for the regulation of the amount of glucose in the blood. If insulin is not produced by pancreas or produced in less amount then it can cause a form of diabetes. Now we can eliminate this option as in the question plant hormone is asked but insulin is the hormone found in the human body.
Moving to the next option i.e., Option B. Thyroxine. This hormone is produced by the thyroid gland which increases the metabolic rate and helps in the growth and development of the body. Thyroid gland is present in the human body so we can eliminate this option too.
Now the option C i.e., Oestrogen. Oestrogen is the female sex hormone which is produced in both males and females. It has major roles in the female reproductive system. It controls puberty and plays a role in the development of the physical body in females. This option is also not related to the plant hormone.
The last option is D i.e., Cytokinin. Cytokinin is the plant hormone which has a major role in growth and development of the plants. It helps in embryogenesis, cell division, chloroplast differentiation and many other important roles in plants. Therefore, it is clear from above the options that cytokinin is the plant hormone.
Thus, the correct answer is option D i.e., Cytokinin.
Note: From all the given options, only Cytokinin is the plant hormone and all the other options given are animal hormones which have different roles in different organs. Cytokinin plays a major role in plants for their growth and development and hence this hormone is really important in plants. Without this hormone, plants won't be able to grow and function properly.
