Final answer:
In Nehru's 'Tryst with Destiny' speech, dedication was likely called for several principles that include unity, democracy, and equality, which align with the broader goals of the Indian National Congress and historical movements like the French Revolution and American Independence.
Step-by-step explanation:
In Jawaharlal Nehru's historic speech "Tryst with Destiny," delivered on the eve of India's independence, he outlined several pledges. These pledges were meant to guide the newly independent nation of India. While the student's question refers to three things Nehru mentioned for dedication.
The speech primarily calls for dedication to the larger causes of the nation, which could be inferred to include unity, democracy, and equality, all integral parts of Nehru's vision for India. However, as for the options provided, one of the things to which Nehru called for dedication in the broader historical context and values inspired by movements like the Indian National Congress and engagements for liberty and equality would likely align most closely with equality.
The Indian National Congress, which played a crucial role in the fight for independence, was driven by principles that included equality and democratic governance, as well as unity. The themes of liberty, equality, and fraternity echo the philosophical underpinnings that also inspired other historical movements like the French Revolution, as suggested in the reference to the "Tennis Court Oath" and the Declaration of Independence.
