**Explanation:**

The agency of social development refers to the factors or entities that play a crucial role in shaping a child's social development. These agencies provide opportunities, experiences, and interactions that contribute to a child's understanding of the world, development of social skills, and formation of their identity. Among the options provided, all of them can be considered as agencies of social development for a child. Let's discuss each of them in detail:

**1. Home:**
The home environment is one of the most significant agencies of social development for a child. Children spend a considerable amount of time at home, and it is within this setting that they learn various social skills, values, and behaviors. The family members, particularly parents, siblings, and extended family, play a crucial role in socializing the child. Through interactions, conversations, and daily routines, children learn about communication, cooperation, empathy, and other essential social skills. Furthermore, the home environment shapes a child's sense of belonging, security, and emotional well-being, which are vital aspects of healthy social development.

**2. Neighbourhood:**
The neighbourhood or community in which a child resides also contributes significantly to their social development. Interactions with neighbours, friends, and other community members provide opportunities for children to learn about cooperation, conflict resolution, cultural diversity, and social norms. Engaging in community activities, participating in local events, and having access to safe and inclusive play spaces can further enhance a child's social skills, sense of belonging, and overall development.

**3. Family:**
Family, as mentioned earlier, is an integral part of a child's social development. It is within the family unit that children learn about their roles, responsibilities, and relationships. Parents and other family members serve as role models, teaching children social values, ethics, and acceptable behaviors. Family interactions and dynamics shape a child's understanding of love, trust, respect, and empathy, which are crucial components of healthy social development. Furthermore, the family provides emotional support, nurturance, and guidance, which contribute to a child's overall well-being and social competence.

**4. All of the above:**
Considering the significance of each agency mentioned above, it becomes clear that all of them contribute to a child's social development. The home, neighbourhood, and family collectively provide a range of experiences, interactions, and opportunities that shape a child's social skills, emotional development, and overall social well-being. By having a supportive and positive environment across these agencies, children can develop strong social competencies, establish healthy relationships, and navigate social situations effectively.

In conclusion, the agency of social development of the child includes the home, neighbourhood, and family. These entities collectively provide the necessary experiences, interactions, and opportunities that shape a child's social skills, values, and overall development. Therefore, the correct answer is option 'D' - All of the above.
