Answer 1

The correct option is D Large amount of information that is generated as trails or by-products of online and offline activities

Big Data refers to a large amount of information that is generated as trails or by-products of online and offline activities — what we purchase using credit cards, where we travel via GPS, what we ‘like’ on Facebook or retweet on Twitter, and so on. Big data was exercised in the 2017 Economic Survey and Annual Budget, shedding new perspectives on the flow of goods, and migration in the country.
