Explanation:
Introduction:
Civil society refers to the space for collective action around shared interests, purposes, and values, generally distinct from government and commercial for-profit actors. It includes a wide range of organizations, such as non-governmental organizations (NGOs), community-based organizations, and faith-based organizations.

Non-Government Organizations (NGOs):
Non-Government Organizations (NGOs) are considered an integral part of civil society. They are independent entities that are not affiliated with the government or any political party. NGOs work towards the betterment of society by addressing various social, environmental, and developmental issues. They play a crucial role in advocating for human rights, promoting social justice, and providing assistance to vulnerable groups.

Caste Associations:
Caste associations, on the other hand, are not considered as part of civil society. Caste associations typically represent specific caste groups and primarily focus on protecting and promoting the interests of their respective castes. While they may engage in activities that benefit their own communities, their primary objective is often limited to advancing caste-based interests rather than working towards the broader goals of civil society.

Legislature:
The legislature, which consists of elected representatives who make laws and govern the country, is also not considered part of civil society. While the legislature plays a crucial role in the functioning of a democratic society, it is a formal institution that operates within the framework of government and is responsible for making and amending laws.

Family:
The family, as a unit of social organization, is not considered part of civil society. The family is a fundamental social institution that is primarily concerned with private and personal matters, such as raising children, maintaining interpersonal relationships, and fulfilling basic needs. While families contribute to the overall fabric of society, they are not typically engaged in collective action or advocacy for broader social issues.

Conclusion:
In conclusion, while non-government organizations (NGOs) and caste associations are part of civil society, the legislature and family are not considered as such. Civil society encompasses a wide range of organizations that work towards the betterment of society and advocate for various social causes.
