Answer:
Trade barriers protect infant industries that initially have relatively high costs ( A )
Step-by-step explanation:
protectionism is an act of protection of local industries made by Government by restricting imports from other countries on goods and services been produced locally by industries in the country. this act is made possible by imposing tariffs on imported goods and services from other countries.
