For low income countries, which of the following is not a basic infrastructure service ?

Telecommunication

The correct answer is option (3) : Telecommunication

In any country, as the income rises, the composition of infrastructure requirements changes significantly. For low-income countries, basic infrastructure services, like irrigation, transport and power, are more important. As economies mature and most of their basic consumption demands are met, the share of agriculture in the economy shrinks and more service-related infrastructure is required. This is why, the share of power and telecommunication infrastructure is greater in high-income countries.
