I was able to achieve this layout using Bootstrap 3, but I am not sure how to implement the same setup with Bootstrap 4 (4.1).
My goal is to have a column displaying C beneath A, and another column displaying B. However, on mobile devices, I want all three elements (A, B, C) to be displayed in a single column. Please refer to the example image provided below.

Any suggestions or help would be greatly appreciated. Thank you!
