The correct answer is the option that states "Elimination of all advertising." This is not a benefit of audience extension because audience extension is a strategy aimed at increasing the effectiveness of advertising campaigns by reaching additional relevant audiences.

Audience extension allows advertisers to reach potential customers who may not have been previously accessible through their standard channels, thereby maximizing exposure and engagement. It supports increased revenue for advertisers as they can tap into a broader customer base. Additionally, it provides more monetization opportunities for publishers since they can sell ad space to advertisers looking to reach extended audiences, facilitating a more diverse range of advertising options. Lastly, a wider audience reach is a primary aim of audience extension, helping to ensure brands connect with an expanded set of individuals who might be interested in their products or services.

In contrast, the notion of eliminating all advertising is counter to the very purpose of audience extension, which seeks to enhance advertising efforts rather than remove them entirely.
