___ was declared as “Ambassador of Hindu-Muslim Unity” by Sarojini Naidu.

Quaid-e-Azam Muhammad Ali Jinnah was famously bestowed the title of "Ambassador of Hindu-Muslim Unity" by the renowned poet and political activist Sarojini Naidu. This recognition came during his early political career, particularly after his instrumental role in forging the Lucknow Pact of 1916, which saw a temporary alliance between the Indian National Congress and the All-India Muslim League. Option A is correct. Allama Iqbal was a philosopher and poet, Liaquat Ali Khan was Jinnah's lieutenant, and Sir Syed Ahmad Khan was a 19th-century reformer; none received this specific title from Naidu.
