Explanation:

The Preamble to the Constitution of India outlines the fundamental values and philosophy on which the Constitution is based. It declares India to be a Sovereign, Socialist, Secular, Democratic Republic and aims to secure for all its citizens: Justice, Liberty, Equality, and Fraternity. - **Option A (Equality):** The Preamble explicitly mentions 'Equality of status and of opportunity' to be secured for all citizens. This is a core ideal of the Indian Constitution, ensuring that all individuals are treated equally before the law and have equal opportunities. - **Option B (Liberty):** The Preamble guarantees 'Liberty of thought, expression, belief, faith and worship'. This fundamental value ensures freedom in various aspects of life for Indian citizens, subject to reasonable restrictions. - **Option C (Sanctity):** The word 'Sanctity' (meaning holiness or sacredness) is not included in the Preamble of the Constitution of India. The Preamble focuses on political, social, and economic ideals, not religious or spiritual sanctity in its descriptive terms for the nation or its goals. - **Option D (Justice):** The Preamble aims to secure for all its citizens 'Justice, social, economic and political'. This is one of the primary objectives, emphasizing fairness and equity in societal relations, economic distribution, and political participation.
