Who was appointed as the head and managing director of Punjab National Bank (PNB) during the banking sector reshuffle referred to in this question?

Introduction / Context:
Public sector bank leadership appointments are frequently tested in banking and general awareness sections, because they affect financial policy and corporate governance. Punjab National Bank (PNB) is one of India largest public sector banks. This question checks whether candidates know who was appointed as its head and managing director at the time described.

Given Data / Assumptions:

The bank involved is Punjab National Bank (PNB).
The role mentioned is that of the head or managing director.
The appointment occurred during a wider banking sector reshuffle.
Four names of senior banking professionals are given as options.

Concept / Approach:
The concept is factual recall of high level appointments in the public sector banking system. While several executives were moved between banks, only one of the listed names took charge at PNB as managing director and chief executive. The correct name to recall in this context is Sunil Mehta.

Step-by-Step Solution:
Step 1: Focus on the bank mentioned, which is Punjab National Bank, and the role of head or managing director. Step 2: Recall the official announcement that Sunil Mehta was appointed as MD and CEO of PNB. Step 3: Match this recollection with option D and choose Sunil Mehta as the correct answer.

Verification / Alternative check:
Official notifications from the Government of India and financial news reports on the banking reshuffle clearly state that Sunil Mehta took over as the managing director and chief executive of PNB. Reviewing these sources confirms that option D is accurate and that the other names are associated with different banks or roles.

Why Other Options Are Wrong:
Dinabandu Mohapatra was associated with another public sector bank and is not the person who headed PNB in this specific appointment, so option A is incorrect.
Usha Ananthasubramanian also served as the head of different banks and not PNB at the time described in the question, so option B is wrong.
R A Narayan does not match the widely reported appointment to the top post at PNB, making option C incorrect.

Common Pitfalls:
Candidates may confuse leaders of different public sector banks because many reshuffles happen around the same period. Another pitfall is relying only on partial memory of news headlines and mixing up which executive went to which bank. Creating a simple table mapping bank names to their managing directors during revision can help avoid such errors.

Final Answer:
The head and managing director of Punjab National Bank mentioned in the question was Sunil Mehta.
