Correct option is C
✅ (c) geometric progression
· Thomas Robert Malthus proposed that population grows exponentially (geometric progression), i.e., doubling every cycle (2, 4, 8, 16, …).
· He suggested that food production increases in arithmetic progression (linear rate), creating imbalance and leading to “Malthusian Crisis”.
❌ (a) ever increasing rate
· While population increases, Malthus specified the pattern as geometric progression, not “ever increasing rate”.
❌ (b) increasing and decreasing rate
· Incorrect, Malthus argued for continuous exponential growth unless checked by external factors like famine, war, or disease.
❌ (d) arithmetic progression
· Arithmetic progression describes food production growth in Malthusian theory, not population growth.
