Step-by-step explanation:
The correct answer is c. Deciding on the colour options for a specific car model. Changing steel suppliers to get a less expensive price for steel is a strategic decision because it involves cost optimization and can impact the profitability of the company. Introducing a new model with advanced safety features to meet changing consumer preferences is also a strategic decision as it involves product development and adapting to market trends. Implementing a new employee training program to enhance manufacturing efficiency is another strategic decision as it aims to improve operational effectiveness. On the other hand, deciding on the colour options for a specific car model is not typically considered a strategic decision. While colours may influence consumer preferences to some extent, they are not a critical factor in the overall strategy of the company.
