The correct answer is: C. (A) is true, but (R) is false.
The assertion (A) is true because international businesses can operate in any country in the world. However, the reason (R) is false because the style of an international business is not limited to the internal economy only. In fact, international businesses often have to adapt their style to the local culture and customs of the country in which they are operating.
For example, a company that sells fast food in the United States might have to change its menu and marketing strategy when it expands to China. This is because Chinese consumers have different tastes and preferences than American consumers. The company would also need to be aware of Chinese cultural norms and avoid any practices that could be considered offensive or inappropriate.
In conclusion, the assertion (A) is true because international businesses can operate in any country in the world. However, the reason (R) is false because the style of an international business is not limited to the internal economy only. In fact, international businesses often have to adapt their style to the local culture and customs of the country in which they are operating.
