Public Affairs Centre (PAC), which conducts action research on Sustainable Development Goals and governance in the Indian context, is situated in which Indian city?

Introduction / Context:
This question is about an important public policy research institution in India and its geographic location. Public Affairs Centre, often abbreviated as PAC, is known for its work on governance, public services, and Sustainable Development Goals. Many general knowledge and current affairs questions ask where such think tanks or institutions are based, since this connects institutional information with city level geography.

Given Data / Assumptions:
• The institution mentioned is Public Affairs Centre (PAC).
• It engages in action research and policy analysis focusing on India.
• We must identify the city where PAC is situated.
• The options are New Delhi, Bengaluru, Mumbai, and Kolkata.

Concept / Approach:
Public Affairs Centre is headquartered in Bengaluru, the capital city of Karnataka. It is not based in New Delhi, which hosts many other think tanks and national institutions, nor in Mumbai or Kolkata, which have their own research organisations. Therefore, the correct approach is to associate PAC with Bengaluru when answering geography based institution questions.

Step-by-Step Solution:
Step 1: Recognise PAC as a governance and public policy research institution in India. Step 2: Recall that its headquarters and main office are located in Bengaluru, Karnataka. Step 3: Look at the options New Delhi, Bengaluru, Mumbai, and Kolkata and identify Bengaluru. Step 4: Eliminate New Delhi because, although many think tanks are located there, PAC specifically is not headquartered there. Step 5: Eliminate Mumbai and Kolkata for the same reason and select Bengaluru as the correct city.

Verification / Alternative check:
The official website and contact information for Public Affairs Centre clearly list Bengaluru, Karnataka, as the location of its headquarters. Many articles and profiles describing the institution also mention it as a Bengaluru based think tank. Standard current affairs capsules that include questions about PAC provide Bengaluru as the correct answer, confirming this city association.

Why Other Options Are Wrong:
New Delhi: Although it is the national capital and hosts many think tanks, it is not the city where PAC is based.
Mumbai: A major financial and commercial hub, but not the headquarters city of Public Affairs Centre.
Kolkata: A major eastern metropolitan city with its own institutions, yet not the home of PAC.

Common Pitfalls:
Because many national level policy discussions occur in New Delhi, candidates may assume that every major policy think tank must be located there. Another pitfall is not differentiating between various institutions and their city locations. To avoid confusion, it is helpful to learn a small set of institution city pairs, such as PAC with Bengaluru and other specific think tanks with their respective cities.

Final Answer:
The correct choice is Bengaluru, since Public Affairs Centre (PAC) is situated there.
