Developmental Attainment Order

This question asks to arrange developmental tasks in the correct chronological order based on typical child development.

Child Skill Progression Breakdown

Skills develop progressively. Generally, gross motor skills and basic self-care tasks appear before complex fine motor skills and cognitive tasks. Let's analyze each item:

• d. Puts on and remove Pajamas: This task relies heavily on gross motor abilities and requires less precision. It is typically mastered earliest, around ages 2-3.
• c. Fastens and unfastens big buttons: This involves developing fine motor skills and hand-eye coordination. It is usually achieved after basic dressing skills, around ages 3-4.
• b. Copies simple letters and shapes: Copying requires more advanced fine motor control and visual-motor integration. This skill typically emerges later, around ages 4-5.
• a. Ties shoe laces: Tying shoelaces is a complex fine motor skill demanding significant dexterity, bilateral coordination, and concentration. It is usually mastered last among these tasks, around ages 5-6.

Correct Developmental Sequence

Based on the typical progression of these developmental attainments, the correct order is:

1. d. Puts on and remove Pajamas (Earliest)
2. c. Fastens and unfastens big buttons
3. b. Copies simple letters and shapes
4. a. Ties shoe laces (Latest)

Thus, the correct sequence is d, c, b, a.
