D Correct answer
Explanation

Trellis drainage pattern develops on folded sedimentary rocks where streams flow along parallel valleys (synclines) and then cut across ridges (anticlines) at right angles, creating a trellis-like pattern similar to a grapevine support system. This is characteristic of alternately resistant and soft rock layers in folded terrain, unlike dendritic (tree-like), radial (spokes), or rectangular (fault-controlled) patterns.
