What is the function of the Quick Selection Tool in Photoshop?

The Quick Selection Tool in Photoshop is specifically designed for quickly selecting parts of an image based on color, texture, and edges. It allows users to paint a selection onto the image by simply clicking and dragging the cursor. This tool is particularly useful for selecting complex areas without the need for intricate manual selections, making it efficient for tasks like isolating subjects, removing backgrounds, or applying adjustments to specific areas of an image.

This capability sets it apart from other tools in Photoshop. For instance, the eraser tool is meant for removing pixels, while adding text involves a different set of functionality focused on text layers. Applying filters, on the other hand, requires selections of entire layers or images rather than specific areas. The primary strength of the Quick Selection Tool lies in its speed and efficiency in making selections, which is why it stands out as the correct answer.
