E) If the assertion is false but reason is true
Correct Answer: A
Solution :
The growth rate is not uniform but is different at different periods of life, so the growth is differential. Growth is rapid in the pre-natal and puberty period (14-18 years). It is slow in the juvenile (5-14 years) and post-adolescent period as there is no addition of living matter in this period.
