This question checks whether you know the specific distance band fixed by India's National TOD Policy, 2017, for the zone of influence around a transit station where compact, high-density, mixed-use development is encouraged.
- 300 to 400: This is far too tight a band. It would cover little more than the station plaza itself, not the wider catchment the TOD policy is meant to shape.
- 500 to 800: This is the band actually fixed by the policy. It reflects the distance an average pedestrian will comfortably cover in about 8 to 10 minutes of walking, the design basis for TOD catchments worldwide and adopted in India's own policy text.
- 600 to 800: This overlaps with the correct band at its upper end but starts too high, missing the 500 to 600 m portion the policy also counts as within the influence zone.
- 400 to 600: The same problem in reverse: it captures part of the true range but stops short of 800 m, cutting off the outer part of the walkable catchment the policy specifies.
Only the 500 to 800 m band matches the policy document exactly, so option (B) is the correct choice.
Let's summarize:
- The TOD influence zone is a walking-distance catchment around a transit station, meant to concentrate density and mixed use where transit access is easiest.
- India's National TOD Policy, 2017 fixes this catchment at 500 to 800 m.
So the correct answer is option (B), 500 to 800 m.
