At which of the following places is the College of Defence Management CDM located in India?

Introduction / Context:
The Indian Armed Forces maintain several specialised training institutions for different aspects of military education, including tactics, strategy and management. The College of Defence Management focuses on imparting higher level training in management concepts to officers of the Army, Navy and Air Force. This question tests knowledge of where this institution is located.

Given Data / Assumptions:

- The institution in question is the College of Defence Management, often abbreviated as CDM. - Four Indian cities with significant military or educational establishments are listed as options. - We are expected to recall the correct city where CDM is based.

Concept / Approach:
The College of Defence Management is located at Secunderabad, which is part of the Hyderabad urban area in Telangana. It functions under the Integrated Defence Staff and provides courses on leadership, logistics and resource management for senior officers. While Pune, Chennai and Dehradun also host important defence academies and training schools, CDM specifically is associated with Secunderabad.

Step-by-Step Solution:
Step 1: Recall that Secunderabad and Hyderabad together form a major military and administrative hub with several army and air force establishments. Step 2: Remember from defence GK notes that CDM is explicitly mentioned as being located in Secunderabad. Step 3: Consider that Pune is home to institutions like the National Defence Academy and Defence services Staff College is located at Wellington near Ooty, not in Pune. Step 4: Dehradun is associated with the Indian Military Academy, not with the College of Defence Management. Step 5: Chennai has naval and other establishments but is not named as the location of CDM in standard references, so choose Secunderabad.

Verification / Alternative check:
Official information from the Indian Armed Forces and defence ministry websites lists the College of Defence Management at Secunderabad. Additionally, competitive exam preparation books that cover important defence institutions provide tables matching CDM with Secunderabad, NDA with Pune, IMA with Dehradun and so on, confirming that Secunderabad is the correct match here.

Why Other Options Are Wrong:
Pune is a major defence education centre but is primarily associated with the National Defence Academy and other institutions, not with CDM. Chennai has important military bases and dockyards but is not the site of the College of Defence Management. Dehradun hosts the Indian Military Academy and other training centres, but the management focussed CDM is not located there.

Common Pitfalls:
Because defence institutions are spread across several cities, students sometimes mix up which academy is in which place. A practical way to avoid confusion is to study a small table that pairs each major institution with its city and to revise it repeatedly. In that table, linking CDM with Secunderabad clearly distinguishes it from NDA in Pune and IMA in Dehradun.

Final Answer:
The College of Defence Management is located at Secunderabad in India.
