Which one of the following Bank is not included in the amalgamation of three public sector banks ?

The correct answer is (d), Punjab National Bank.

The three public sector banks that were amalgamated were Bank of Baroda, Dena Bank, and Vijaya Bank. The new bank, which was formed on April 1, 2019, is called the Bank of Baroda.

Punjab National Bank was not included in the amalgamation because it was already the largest public sector bank in India. The amalgamation of the three banks was seen as a way to create a stronger and more efficient bank that could compete with private sector banks.

The amalgamation of the three banks was a complex process that involved a lot of planning and coordination. The new bank, Bank of Baroda, is now the third largest bank in India by assets.
