Which of the following is the correct purpose of the "taxiway ending" marker?

Taxiway ending markers are yellow and diamond-shaped, with a black border. They are typically located at the end of a taxiway, or at an intersection where the taxiway does not continue.
The purpose of the taxiway ending marker is to alert pilots that they are approaching the end of the taxiway and that they need to make a decision about where to go next.
