Plane (gliding) joints allow a simple gliding movement, such as the acromioclavicular joint. Which option names this joint type?

Explanation:
Plane joints are defined by nearly flat articular surfaces that permit simple gliding movements between bones. The acromioclavicular joint is formed by flat facets of the clavicle and the acromion, so the bones slide past one another with small translational movements as the shoulder moves. This gliding action fits the plane (gliding) joint classification, rather than hinge (which moves in one plane like a door), ball-and-socket (multi-directional movement and rotation), or pivot (rotation around a single axis).
