Final answer:
The primary reason behind the inaccessibility of most potential consumers is limited purchasing power. Geographical barriers and diverse regional languages also contribute to inaccessibility.
Step-by-step explanation:
The primary reason behind the inaccessibility of most of the 1.3 billion potential consumers is limited purchasing power. Many people in developing countries may not have the financial means to afford certain products or services. This can be due to factors such as low income levels, high poverty rates, or economic instability.
For example, in countries with a large population living below the poverty line, such as India, a significant portion of the population may struggle to afford basic necessities, let alone luxuries or imported goods.
Additionally, geographical barriers and diverse regional languages can also contribute to inaccessibility. Countries with diverse geographic landscapes, like China and India, may have areas that are difficult to reach, making it challenging to distribute products effectively. Moreover, the existence of multiple regional languages can pose communication barriers, hindering companies' ability to market their products and reach potential consumers.
