Which campaign was started immediately after demonetization to investigate tax evaders of undeclared income under the tax system?

Correct option is A

The correct answer is (a) Swachh Dhan Abhiyan (Clean Money Campaign)
Explanation:
· Operation Clean Money (Swachh Dhan Abhiyan) was launched by the Income Tax Department (CBDT) on January 31, 2017.
· It was initiated immediately after the demonetization of ₹500 and ₹1,000 currency notes (announced on November 8, 2016).
· The primary objective was to investigate tax evaders and verify cash deposits made during the demonetization window (November 9 to December 30, 2016) that did not match the declared income profile of the depositors.
Information Booster:
· The operation used Data Analytics to identify suspicious deposits.
· It promoted the shift towards a digital economy and aimed to widen the tax base.
· A dedicated portal was launched for taxpayers to submit their responses online without visiting the Income Tax office.
