The correct answer is: C. January 27.
Lal Bahadur Shastri was the second Prime Minister of India. He served from 1964 until his death in 1966. He is remembered for his role in the Indo-Pakistani War of 1965 and for his “Jai Jawan, Jai Kisan” (Hail the Soldier, Hail the Farmer) slogan.
Shastri died on January 27, 1966, in Tashkent, Uzbekistan, while attending a summit meeting with Pakistani President Ayub Khan. His death was officially ruled a heart attack, but there have been persistent rumors that he was poisoned.
Shastri’s death anniversary is a national holiday in India. It is observed on January 27 each year.
