If density is very low in an area and population does not rise even after a road is built which reason should be examined?

Correct answer: Employment water safety and service availability

Direct answer: Option A is correct. A road improves physical access, but people usually consider several conditions before moving or settling: jobs and income, reliable water, safety, schools, health care, markets, electricity and other services. If these conditions remain weak, a new road alone may not attract a lasting population increase. Planners should therefore investigate whether employment exists, whether water is secure and whether essential services are available. Option B cannot explain settlement decisions because road colour has no meaningful effect on population distribution. Option C identifies a vehicle, not the broader economic and social conditions. Option D may describe a physical feature but does not by itself explain the failure of settlement growth. Memory cue: connectivity helps, but people settle where livelihoods and basic services are viable.
