Answer:
a. Meitneria will import textiles from Seaboria and export heavy machinery to it.
Step-by-step explanation:
The Heckscher-Ohlin theory states that a country has to export what it can produce efficiently according to the factors of production that the country has and import the products that the country is not able to manufacture efficiently. According to this, the answer is that in this situation, according to the Heckscher-Ohlin theory Meitneria will import textiles from Seaboria and export heavy machinery to it as Meitneria doesn't produce textiles which forces the country to import them and they specialize on heavy machinery which allows them to export it to Seaboria as this country doesn't have the technology to manufacture it.
