Correct answer: Lal Bahadur Shastri.
Lal Bahadur Shastri, the second Prime Minister of India, coined this slogan during the 1965 India Pakistan war. It means hail the soldier, hail the farmer, and was meant to honor both the soldiers defending the country and the farmers feeding it.
The slogan became popular at a time when India faced both a war and a food shortage, and it reminded citizens that the army and agriculture were equally important for the nation.
