To solve the task of arranging the postural deformities from toe to head, we need to understand each deformity's location in the body:
Arranging these from lowest (toe) to highest (head), the sequence will be:
(C) Pes Planus,
(B) Genu Varum,
(D) Hollow Back,
(A) Hump Back/Kyphosis
Thus, the correct order is (C), (B), (D), (A).

| List-I | (Postural Deformities) | List-II | (Corrective Measures) |
| A | Knock Knees | (I) | Walking on inner edge of feet |
| B | Round Shoulders | (II) | Horse Riding |
| C | Kyphosis | (III) | Wall stretch, Pull Ups |
| D | Bow Legs | (IV) | Swimming, Gym ball exercises |
