What is shown in the image?

The correct answer is B. Divided road ends, keep to the right. The image most likely shows a transition from a divided highway to a non-divided road, indicating that the road will no longer be divided ahead and drivers should keep to the right side. This sign is important for drivers to be aware of upcoming changes in road conditions and adjust their driving accordingly.

Option A, Divided road ahead, is incorrect because the image does not show the beginning of a divided road.

Option C, Narrow bridge ahead, is incorrect because there are no indications of a narrow bridge in the image.

Option D, Road under construction, is also incorrect as there are no signs of road construction in the image.
