As demonstrated by the Nike example in the text, which working conditions situation is generally MOST preferred?

requiring good conditions in home and foreign operations even when this results in a smaller profit margin

meeting required home standards, but permitting the use of child labor in the foreign country as is the norm there

having good working conditions in its home operations, but holding its foreign operations to the lower standards that are acceptable in that country

requiring good conditions in home and foreign operations, but accepting subcontractor safety violations if it's more profitable
