Hey there!
The correct answer is "B."
Digging is the method that involves controlling an invasive species by removing plants from their roots.
Digging is used for multiple things, but this is one of them.
Smother - This means to kill, so this is incorrect.
Mulching - This is a substance that is applied on plants, this is incorrect.
Mowing - This is to remove pieces of grass, so this is also incorrect.
Therefore, your answer is B.
Hope this helps, have a wonderful day! :)
