Who among the following officers took over as the twenty fifth Director General of the Border Roads, that is, the head of the Border Roads Organisation responsible for constructing and maintaining strategic roads in border areas?

Introduction / Context:
The question is about a key appointment in the Border Roads Organisation, an important organisation that constructs and maintains strategic roads and related infrastructure in border and remote areas. Knowing who took over as the twenty fifth Director General of the Border Roads helps candidates track defence and infrastructure related current affairs, which frequently appear in competitive exams.

Given Data / Assumptions:

• The post mentioned is Director General of the Border Roads, often shortened to DGBR.
• The question specifically asks about the twenty fifth person to hold this office.
• Four names of senior army officers of the rank Lieutenant General are listed as options.
• Candidates must recall which of these officers actually took charge as DGBR.

Concept / Approach:
This is a pure recall based current affairs question. The usual approach is to connect the name of the officer with related news reports on defence appointments. Lt. Gen. Sanjeev Kumar Shrivastava was reported as taking over as the twenty fifth DGBR, so his name has to be selected from the list.

Step-by-Step Solution:
Step 1: Identify that the Border Roads Organisation is headed by the Director General Border Roads.Step 2: Recall recent news about a new DGBR taking over as the twenty fifth incumbent.Step 3: Match this recollection with the names in the options.Step 4: Recognise that Lt. Gen. Sanjeev Kumar Shrivastava was the officer mentioned as the new DGBR.

Verification / Alternative check:
A simple verification is to remember that Lt. Gen. Suresh Sharma has been associated with the post of Engineer in Chief in the Indian Army rather than DGBR. David R. Syiemlieh is known for his role in the Union Public Service Commission, and not as head of the Border Roads Organisation.

Why Other Options Are Wrong:
Option A: Lt. Gen. Suresh Sharma held different senior engineering appointments but was not the twenty fifth DGBR.
Option B: Lt. Gen. David R. Syiemlieh served as acting chairman of the UPSC, not as Director General Border Roads.
Option C: Lt. Gen. Srikanth Mishra is not associated in the news with this appointment.

Common Pitfalls:
Candidates may confuse different senior Lieutenant Generals holding various engineering or administrative posts and pick the wrong name. Another pitfall is not keeping track of defence related current affairs in detail and only remembering ranks instead of specific posts.

Final Answer:
The twenty fifth Director General of the Border Roads was Lt. Gen. Sanjeev Kumar Shrivastava.
