Final answer:
The option suggesting that political instability in New Zealand could pose risks for direct investment most weakens the argument for direct investment since it adds unpredictability and increased operational risk, contrary to the long-term stability sought in direct investments.
Step-by-step explanation:
The question posed concerns the strategic decision-making process of The Peterson Group in potentially moving its production operations to New Zealand, with two options on the table: contract manufacturing or direct investment. Considering the argument for direct investment, an aspect that would weaken this argument would be a factor that increases the risk or reduces the potential benefits of such a move. Of the options provided, (c) Political instability in New Zealand could pose risks for direct investment is most likely to weaken the argument for direct investment because political instability can increase operational risk, lead to unpredictable changes in the business environment, and make it difficult to establish a stable long-term presence in the country, which is a key consideration for direct investment.
