If a Foreign Country Follows the 'Purchase Homemade Products' Philosophy

If a foreign country follows the 'Purchase Homemade Products' philosophy, the least effective strategy would be for a UK firm to:

A) use a licensing arrangement with a local firm in that country.
B) enter into a joint venture in that country.
C) develop a subsidiary (under the US name) that manufactures and sells products in that country.
D) develop a subsidiary (under the US name) that manufactures products in that country and exports them to border countries.
