Relaxin causes laxity of the collagen attachments of which structure?

Explanation:
Relaxin promotes laxity of connective tissue by reducing collagen cross-linking, making ligaments and attachments more compliant. In the hoof, the digital cushion is a soft tissue pad that relies on collagen attachments to the distal phalanx (P3) to stay anchored and to cushion impact. When relaxin loosens these collagen attachments, the digital cushion’s connection to the bone becomes lax, reducing its ability to absorb shock and stabilize the digit. The other options refer to bones (P3, P2, calcaneus), which aren’t the soft-tissue attachments that relaxin typically loosens in this context.
