**Question:** A female child has recently learned to eat with a spoon without spitting, to dress and undress herself with supervision, and to understand that she is a girl. These skills are first mastered between the ages of –

A. 18 months to 2 years
B. 24 months to 3 years
C. 36 months to 4 years
D. 48 months to 5 years

**Correct Answer:** D. 48 months to 5 years

**Core Concept:** Developmental milestones refer to significant changes in behavior, cognitive, or motor abilities that occur during infancy and childhood. These milestones provide an understanding of the expected developmental progress of an individual based on their age.

**Why the Correct Answer is Right:** The correct answer, D, represents the typical age range in which children begin to exhibit certain skills, such as eating with a spoon, dressing, undressing themselves, and understanding gender identity.

1. **Eating with a spoon (Cognitive and Motor Skills):** This skill is a part of the "Puree Feeding" stage, which occurs between 4 and 5 years of age. At this stage, children demonstrate improved hand-eye coordination, cognitive development, and a better understanding of utensils, allowing them to eat with a spoon without spitting.

2. **Dressing and Undressing (Cognitive Skills):** Between 4 and 5 years, children are able to understand the concept of dressing and undressing. They can put on and take off clothes independently, demonstrating their growing cognitive abilities and understanding of personal hygiene.

3. **Understanding Gender Identity (Cognitive and Social Skills):** Around the age of 4 to 5 years, children begin to understand their gender identity and the concept of being a girl or boy. This understanding is essential in forming social relationships and adapting to societal norms.

**Why Each Wrong Option is Incorrect:**

A. **48 months to 2 years (Option A):** This option is incorrect because these skills are typically developed later in the second year of life, not at the end of the first year or beginning of the second year.

B. **24 months to 3 years (Option B):** Although some children may achieve these milestones by around 24-36 months, the majority of children exhibit these skills between 4 and 5 years. As mentioned earlier, these skills are associated with the development of cognitive and motor skills, including understanding gender identity.

C. **36 months to 4 years (Option C):** While some children may achieve these milestones at around 36 months, the majority of children develop these skills between 4 and 5 years, which is why this option is incorrect.

D. **48 months to 5 years (Option D):** This option accurately represents the typical age range for achieving these milestones, which is why it is the correct answer. Children between 4 and 5 years can independently perform tasks like eating with a spoon, dressing and undressing, and understanding their gender identity, indicating their cognitive, motor, and social
