What is shown in the image?

In this image, the sign depicts a "Yield" sign, which is used to inform drivers that they must give the right-of-way to oncoming vehicles or pedestrians. When approaching a yield sign, drivers are required to yield to other traffic and proceed when it is safe to do so. This sign is placed in areas where there may be merging traffic or intersections where drivers need to wait for a safe gap to merge into the flow of traffic. Therefore, the correct answer is A - "You must give the right-of-way."

Option B is incorrect because yielding means giving the right-of-way, not taking it. Option C is incorrect as there is no indication of a slow-moving farm vehicle in the image. Option D is also incorrect as the sign does not indicate merging with other traffic but rather yielding to it.
