Screen Time and App Limits

Hi, My objective is to set a total screen time limit for my daughter’s handphone for two hours. But within this 2 hours, I would also like to set certain limits for certain apps, such as a limit for Instagram at 20 minutes and a limit for WhatsApp at 40 minutes. If I were to add three entries to the app limits list:

1. All apps at 2 hours,

2. Instagram at 20 minutes, and

3. WhatsApp at 30 minutes,

would the result be:

A. That she can only use a total of 2 hours per day, within which her use of instagram is limited to 20 minutes and WhatsApp to 30 minutes?

B. Or can she use a total of 2 hours AND 50 minutes per day, which includes 2 hours of any app (including instagram and WhatsApp) and an additional 20 minutes of Instagram and additional 30 minutes of WhatsApp?

Is the answer A or B or something else? Thanks.
