Appeared in: AIIMS CRE SNO - 2023

Explanation

The question most likely refers to the period when Kolkata Metro had three main operational lines.
These three lines are the North-South Corridor (Blue Line), the East-West Corridor (Green Line), and the Joka-Esplanade Corridor (Purple Line).
The Blue Line (Line 1) was the first and is the oldest metro line in India.
The Green Line (Line 2) and Purple Line (Line 3) were added later, bringing the total to three major operational corridors before recent 2024 expansions.

Option A: The number 6 does not correspond to the number of operational metro lines in Kolkata, either in the past or present.
Option B: The number 9 is an inaccurate count of the operational metro lines in Kolkata.
Option C: The number 15 is far greater than the actual number of operational lines and may relate to a future master plan, but it is not the current reality.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain General knowledge about major public transportation systems in India as background academic context rather than a clinical decision trigger.
Efficient public transport systems like the metro are crucial for urban public health. They provide reliable and affordable access to hospitals and healthcare facilities for patients, especially those with chronic conditions requiring regular visits.
For healthcare workers, including nurses, the metro offers a dependable mode of commute, ensuring timely arrival at their workplace, which is critical for maintaining hospital staffing levels.
What if a major hospital is located far from a metro line? This would pose a significant accessibility challenge for low-income patients and staff, potentially leading to delayed care and increased transportation costs. It underscores the importance of integrated urban and health infrastructure planning.

How to Approach the Question

First, read the question carefully to understand what is being asked. This is a general knowledge question about the Kolkata Metro.
Review the options provided: 6, 9, 15, and 3.
Access your general knowledge about major Indian cities and their infrastructure. Recall or look for the most current information on the Kolkata Metro.
Notice that recent news (as of 2024) indicates more than 3 lines are operational, but 4 is not an option. This suggests the question may be slightly outdated.
Evaluate the given options. The numbers 6, 9, and 15 are significantly higher than the known number of lines. The number 3 was the correct count for a long time before the recent expansions.
Conclude that 3 is the most plausible answer among the choices, representing the state of the network when the question was likely created. Select this as the best fit.
