Match the postural deformities listed in List-I with their corrective measures listed in List-II:

The correct option is (A)- (I), (B)- (III), (C)- (IV), (D)- (II).

Here is a detailed, step-by-step explanation of the matching between postural deformities and their corrective measures as shown in the table:

1. (A) Knock Knees matches with (I) Walking on inner edge of feet:
Knock knees (genu valgum) is a postural deformity where the knees bend inward and touch each other when standing, while the ankles remain apart. Walking on the inner edge of the feet (along with other specific foot/leg positioning exercises) helps in correcting the alignment and strengthening the muscles that support the knee joint.

2. (B) Round Shoulders matches with (III) Wall stretch, Pull Ups:
Round shoulders is a postural deformity in which the shoulders become hunched forward. Exercises like pull-ups and wall stretches help strengthen the posterior shoulder and upper back muscles (such as the rhomboids and trapezius) while stretching the tight chest muscles (pectorals), thereby pulling the shoulders back into their natural alignment.

3. (C) Kyphosis matches with (IV) Swimming, Gym ball exercises:
Kyphosis is an abnormal outward curvature of the upper thoracic spine, commonly referred to as a hunchback. Corrective measures include swimming (especially backstroke) and gym ball exercises (such as backward extensions over the ball), which help stretch the chest, strengthen the core and spinal extensors, and restore proper posture.

4. (D) Bow Legs matches with (II) Horse Riding:
Bow legs (genu varum) is a postural deformity where the knees remain wide apart when a person stands with their feet together, resulting in an outward curvature of the legs. Horse riding is a highly recommended corrective measure because the riding posture forces the knees inward to grip the horse, which helps counteract the outward bowing structure.
