Answers
ANSWER:-
The SRS is a demographic survey for providing reliable annual estimates of infant mortality rate, birth rate, death rate and other fertility and mortality indicators at the national and sub-national levels.
Initiated on a pilot basis by the Registrar General of India in a few states in 1964-65, it became fully operational during 1969-70.
The field investigation consists of a continuous enumeration of births and deaths in selected sample units by resident part-time enumerators, generally Anganwadi workers and teachers; and an independent retrospective survey every six months by SRS supervisors.
The data obtained by these two independent functionaries are matched.
So according to this is will be option(A) sample registration system.
