Question

countries establish internal economic zones in order to
limit foreign investment.
make solving disputes easier.
create manageable amounts of imports.
have fewer economic restrictions.

Explanation:

Internal economic zones (like free - trade zones) are set up to promote economic activities. Having fewer economic restrictions is a key goal as it encourages trade, investment, and business operations within the zone. Creating manageable import amounts is more about import quotas which is not the main purpose of internal economic zones. Making dispute solving easier is not the primary aim of establishing such zones. Limiting foreign investment goes against the purpose of these zones which usually aim to attract investment. So the correct option is the one with "have fewer economic restrictions".

Answer:

The option with "have fewer economic restrictions"
