a) Malthus ignored other factors like technological change.
Explanation:
Thomas Malthus (1766-1834) was an English cleric and a scholar, most known for his demographics theory. He is an author of <em>An Essay on the Principle of Population</em>, where he observed that increasing production of food resulted in improved well-being of the population, but this was temporary because it led to a population growth. Larger population led to the restoration of original production per capita.
