Answer:
A. Both conclusions wish other nations of the world well, but Chamberlain advocates imperialism, while Nehru advocates freedom for India.
Explanation:
Joseph Chamberlain's (8 July 1836 – 2 July 1914) concluding phrase <em>"future union with the British races throughout the world"</em>, the title of the text <em>"I Believe in a British Empire"</em> and the start of the text all show that Chamberlain is advocating British imperialism.
Jawaharlal Nehru's (14 November 1889 – 27 May 1964) <em>"the eternal and the ever-new, we pay our reverent homage and we bind ourselves afresh to her service</em>" and <em>"pledge ourselves to cooperate with them in furthering peace, freedom and democracy."</em> show that he is advocating freedom for India as well as democracy and peace.
Option B is not correct as Chamberlain says nothing about religion, is against separate England. And Nehru clearly demands freedom for India.
Option C is not correct Because Nehru says nothing directly about British people.
Option D is not correct because Chamberlain's text says nothing about peace, and Nehru's text nothing about competition.
