Step-by-step explanation:
The sign that indicates traffic merging from the right and to prepare to allow traffic to safely merge is the Yield sign (B).
The Yield sign is a triangular sign with a red border and a white interior. It is used to alert drivers to be ready to stop if necessary and yield the right-of-way to other vehicles approaching from the right or left.
For example, suppose you are approaching an intersection and see a Yield sign. In that case, you should slow down, check for any oncoming traffic, and yield to any vehicles already in the intersection or approaching from the other direction.
