DTwenty years
Correct answer: (B) Five years
Explanation
The NSSO conducts its survey on education and employment every five years.
These are known as its quinquennial rounds.
The five-year cycle balances currency of data against survey cost.
A one-year interval would be too frequent and costly for such large rounds.
Ten or twenty year gaps would leave the data badly outdated.
The NSSO now functions under the National Statistical Office.
