Consider the following scenarios in SaaS businesses and determine which ones correctly represent the definition of an 'Activated User':
- Scenario I: A user subscribes to a project management tool, completes the onboarding process, and starts using the core project tracking features regularly.
- Scenario II: A user signs up for a graphic design software, but only uses it once for a one-off task of adding digital signature and doesn't explore its core functionalities.
- Scenario III: After a free trial of a CRM system, a user subscribes to a paid plan and begins integrating it into their daily sales activities.
- Scenario IV: A user of a data analysis platform completes the onboarding process and regularly uses the platform's advanced analysis tools to generate insights.
