Break activity within 2 For each activities. How many loops are stopped?

I have 2 For Each Row activities, For Each Row ‘A’ and For Each Row ‘B’.

For Each Row ‘B’ is within the body of For Each Row ‘A’.

If I use one Break activity in For Each Row ‘B’ only, does it break the loop for For Each Row ‘B’ or will it break the loop for both For each Row ‘A’ and ‘B’.

Example:

@dvn Only For Each Row B
