If the gingival margin is at CEJ level, CAL is equal to the pocket depth.

Explanation:
When the gingival margin sits at the cementoenamel junction, the clinical attachment level becomes the same distance as the pocket depth. CAL is defined as the distance from the CEJ to the base of the pocket, while probing depth is the distance from the gingival margin to the base of the pocket. If the gingival margin is at the CEJ, the distance from CEJ to base equals the distance from GM to base, so CAL equals the probing depth. The term used for that pocket distance is probing depth, making it the best answer in this scenario.
