Step-by-step explanation:
The property that an international market segment should ideally possess in a target country where there are differences in the quality of the media infrastructure is accessible.
Accessible refers to the ability of the market segment to effectively reach and engage with the target audience in a particular country, despite variations in media availability or infrastructure.
For example, if a target country has limited access to commercial television, an international market segment must adapt its marketing strategies to utilize alternative media channels, such as radio, print, or digital platforms like social media, to effectively reach and communicate with the audience.
