Final answer:
The correct option is A). Investing in tamper-proof packaging is likely to initially increase a company's expenses, but may also have long-term benefits such as market share expansion and profit stability.
Step-by-step explanation:
Investing in "tamper-proof packaging" is most likely to result in an increase in expenses for a company. This is because implementing new packaging technology often involves upfront costs such as research and development, equipment, and training for staff. However, while it may increase expenses in the short term, tamper-proof packaging can lead to long-term benefits such as deterring product tampering, increasing consumer trust, and potentially justifying a higher price point, which may lead to expansion of market share and potentially stability in profits if the product becomes preferred due to safety features.
