Using flexible expansion joints primarily accommodates movement within tile installations, making this choice correct. Expansion joints are designed to manage the natural expansion and contraction that occurs due to temperature fluctuations and other environmental factors. This ability to absorb movement helps to prevent stress and cracking in the tiles or the substrate beneath them, ultimately enhancing the longevity and durability of the tiled surface.

In contrast, while the other options may offer various benefits in specific contexts, they do not encapsulate the primary purpose of flexible expansion joints. For instance, ease of cleaning may vary and is not a fundamental characteristic of these joints. Similarly, while cost and installation procedures can be factors in specific projects, the most significant advantage of flexible expansion joints lies in their capacity to handle movement, ensuring structural integrity over time. Reducing the need for grout relates to installation complexity rather than the fundamental function of expansion joints, so this does not accurately reflect their primary advantage.
