As of February 2018, who was appointed as the new Governor of Tamil Nadu?

Introduction / Context:
The post of Governor is an important constitutional office at the State level in India. Current affairs questions frequently ask about new appointments, transfers and additional charge arrangements for Governors. This question specifically targets your memory of who held the office of Governor of Tamil Nadu around February 2018.

Given Data / Assumptions:

• The question clearly mentions the time reference as February 2018.
• It asks for the person who was appointed as the new Governor of Tamil Nadu at that time.
• Options include Banwarilal Purohit, K Rosaiah, Satyapal Malik, Subramanian Swamy and C Vidyasagar Rao.
• Banwarilal Purohit took charge as Governor of Tamil Nadu in late 2017 and continued in 2018.

Concept / Approach:
Governors are appointed by the President and often shifted from one State to another. Sometimes an existing Governor holds additional charge of another State until a full time Governor is appointed. For Tamil Nadu, C Vidyasagar Rao earlier held additional charge, after which Banwarilal Purohit was appointed as the regular Governor. To answer correctly, you must match the time period and the person who actually held the office as substantive Governor.

Step-by-Step Solution:
Step 1: Recall that C Vidyasagar Rao, Governor of Maharashtra, had additional charge of Tamil Nadu for some time. Step 2: Remember reading that Banwarilal Purohit, previously Governor of Assam, was appointed as the new full time Governor of Tamil Nadu. Step 3: Note that this appointment was effective by the end of 2017, and therefore he was in office during February 2018. Step 4: Compare this information with the list of given options. Step 5: Select Banwarilal Purohit as the correct answer and rule out the other names.

Verification / Alternative check:
One way to check is to see how coaching material describes the sequence: first additional charge by C Vidyasagar Rao, then appointment of Banwarilal Purohit as the new Governor. K Rosaiah had served earlier as Governor of Tamil Nadu, but his tenure ended before this period. Satyapal Malik is linked to other States like Jammu and Kashmir and later Goa and Meghalaya, while Subramanian Swamy is a Member of Parliament and economist, not a Governor. This pattern confirms that Banwarilal Purohit alone fits the time frame and role.

Why Other Options Are Wrong:
K Rosaiah: He did serve as Governor of Tamil Nadu in the past, but not as the newly appointed Governor as of February 2018.
Satyapal Malik: Known for holding gubernatorial posts in different States, but not in Tamil Nadu at this particular time.

Subramanian Swamy: A senior political leader and parliamentarian, but never appointed as Governor of Tamil Nadu.

C Vidyasagar Rao: Held additional charge earlier, however he was not the new substantive Governor in February 2018.

Common Pitfalls:
Candidates may confuse earlier Governors with the one currently in office at a given date, especially when there is an overlap with additional charge arrangements. Another mistake is to mark a very familiar political name, even if that person has not actually held the gubernatorial office in that State. Careful reading of dates and designations in current affairs notes prevents such errors.

Final Answer:
As of February 2018, the Governor of Tamil Nadu was Banwarilal Purohit.
