According to Malthus population grows

Arithmetically
Geometrically
At constant rate
None of the above

According to Malthus, population grows geometrically, while food production grows arithmetically. This means that population growth is exponential, while food production is linear. As a result, population will eventually outstrip food production, leading to famine and starvation.

Option A is incorrect because population growth is not arithmetical. Option B is correct because population growth is geometrical. Option C is incorrect because population growth is not at a constant rate. Option D is incorrect because Malthus did believe that population growth would eventually outstrip food production.
