The Agile framework that involves Scrum Masters meeting frequently to better coordinate work on a single product across teams is Scrum of Scrums.

Here's a step-by-step explanation:

1. Scrum of Scrums: This is a scaled agile framework that is designed to coordinate work across multiple Scrum teams. Each Scrum team has its own Scrum Master, and these Scrum Masters meet regularly in a "Scrum of Scrums" to discuss their work and coordinate efforts. This makes it the correct answer.

2. Disciplined Agile Delivery (DAD): This is a decision-making toolkit that focuses on the delivery of complex, enterprise-class software. It doesn't specifically involve Scrum Masters meeting frequently.

3. Large-Scale Scrum (LeSS): This is a framework for scaling Scrum up to many teams. It does involve coordination across teams, but it doesn't specifically involve Scrum Masters meeting frequently.

4. Scaled Agile Framework (SAFe): This is an online, freely revealed knowledge base of proven success patterns for implementing Agile at enterprise scale. It involves coordination across teams, but it doesn't specifically involve Scrum Masters meeting frequently.
