Which of these countries would be most likely to face the greatest obstacles to economic development?

a coastal tropical country
a country with a largely uneducated population
a small land-locked country
a country with little or no industry
an arid country with untapped mineral resources

A small land-locked country

Explanation:

A landlocked country shall face the greatest obstacle to development.

This is because by being landlocked, it cannot access the outside world.

No international business shall happen between the country and others, thereby no foreign revenue shall be earned by the country.

Access to a country is primary in its business dealings with other countries, thereby a landlocked country is an economically maimed country.
