Which among the following is the most logical and rational inference that can be made from the passage given above ?

Correct Option: (c) To maintain and develop our cities we need to adopt sustainability related interventions.

The passage highlights that cities are vulnerable to climate change due to dense populations and poor infrastructure, yet they contribute 65% to the GDP. It stresses addressing air quality, transport, and involving citizens to find sustainable solutions. Therefore, the most logical inference is that to maintain and develop cities, we must adopt sustainability-related interventions. Option (a) is about administrative setup, which is not the primary thrust. Option (b) mentions population density as a hindrance, but the passage points to lack of systems and infrastructure as the core problem. Option (d) introduces Public-Private Partnership, which is outside the scope of the passage.
