b)Birth control
c)Literacy programme
d)Migration to other states

Answer 1

Hint: The "population growth rate" can be defined as the rate at which the number of individuals in a population increases in a given time period, expressed as a fraction of the initial population. Population growth rate depends on birth rate , death rate and migration.

Complete answer: During the decade 2001 to 2011, Karnataka had a decadal growth rate of 15.67 %. During the same decade India had a growth rate of 17.64%. Population decreases when birth control is promoted and made accessible. Access to birth control helps to avoid unwanted pregnancies and decreases size of population.
-Literacy programmes help in population decrease as more girls are educated ,they become aware of their rights and the age of marriage gets increased as they pursue higher education. Literacy also helps people understand sexual education and plan their family better.
-Family welfare programmes as well as access to sterilization services helped to bring down the birth rate.
-However, migration to other states is not a reason for decrease in population growth as Karnataka has higher inflow of migrants because of pull factors the state has like educational opportunities, mineral industries as well as jobs in the corporate and IT sector.

Therefore option (D) is the correct answer.

Note: Kerala has the lowest decadal population growth rate at 4.6%. On the other hand, Bihar has the highest decadal growth rate at 28.6%.
