'Jai Jawan Jai Kisan' as a famous slogan was given by :

Lal Bahadur Shastri

The correct answer is option (2) - Lal Bahadur Shastri

Lal Bahadur Shastri held the position of India's Prime Minister from 1964 to 1966. During this relatively brief period, the nation confronted two significant and pressing challenges. The aftermath of the conflict with China and its economic implications persisted, while the combination of failed monsoons, drought, and an acute food crisis posed a grave dilemma. Additionally, as previously explored, India engaged in a war with Pakistan in 1965. Symbolizing the nation's determination to address these adversities, Shastri's renowned slogan 'Jai Jawan Jai Kisan' became a beacon of resolve.
