American financial magazine Barron has included the Managing Director of HDFC Bank in its list of the world thirty best Chief Executive Officers. What is the name of this HDFC Bank Managing Director?

Introduction / Context:
This question is drawn from business and banking current affairs. It deals with international recognition given by Barron, an American financial magazine, to prominent global Chief Executive Officers. Specifically, it asks for the name of the HDFC Bank Managing Director who was placed on the list of the world thirty best CEOs.

Given Data / Assumptions:

• The magazine is Barron, known for financial analysis and rankings.
• The recognition is a place in a list of the world thirty best CEOs.
• The person is the Managing Director of HDFC Bank.
• Four names are given as options.

Concept / Approach:
HDFC Bank, one of India leading private sector banks, is closely identified with Aditya Puri, who served as its long time Managing Director. Barron often features global banking leaders in such lists, and Aditya Puri was recognised for building HDFC Bank into a high quality, well governed financial institution. The question is essentially a direct recall of this fact.

Step-by-Step Solution:
Step 1: Identify the bank as HDFC Bank and think of its well known Managing Director.Step 2: Recall that Aditya Puri has been the face of HDFC Bank for many years.Step 3: Remember news reports stating that Barron included Aditya Puri among the world top thirty CEOs.Step 4: Choose Aditya Puri from the options.

Verification / Alternative check:
Another check is to notice that the other names in the options are not commonly associated with the post of HDFC Bank Managing Director. For instance, M K Sharma is linked with other roles, and the remaining names do not match well known HDFC Bank leadership.

Why Other Options Are Wrong:
Option B: Sanjeev Misra is not the HDFC Bank Managing Director recognised in this context.
Option C: M K Sharma is not identified with this specific honour regarding HDFC Bank in Barron rankings.
Option D: Shikha Singh is also not linked with the top executive role mentioned.

Common Pitfalls:
Some candidates may not clearly remember who leads which private sector bank and may guess based on partial familiarity with names. To avoid such confusion, it is helpful to maintain a short list of key banking leaders while preparing for exams.

Final Answer:
The HDFC Bank Managing Director named among the world thirty best CEOs by Barron was Aditya Puri.
