Explanation:

• The Sample Registration System (SRS) is a large-scale demographic survey for providing reliable annual estimates of Infant mortality rate, birth rate, death rate and other fertility & mortality indicators at the national and subnational levels conducted by Office of the Registrar General, India. Recently SRS Bulletins with reference year 2018 have been released.

• Birth Rate is a crude measure of fertility of a population and is a crucial determinant of population growth. It gives the number of live births per thousand population in a given region and year.

• Infant Mortality Rate is defined as the infant deaths (less than one year) per thousand live births in a given time period and for a given region. Both have seen continuous decline in India in last decade.

• Maternal Mortality Ratio (MMR) is defined as the number of maternal deaths per one lakh live births. India has delivered an overall improvement in the maternal mortality ratio (MMR) to 97 deaths per one lakh live births in 2018-20 from 130 per lakh in 2014-2016, as per the Health Ministry. 

Hence all statements are correct.
