Answer: Option D
Answer: (d)
When a country goes through industrialization, it uses more capital and less labour comparatively or we can say labours are replaced by capital (machinery). That means ratio of capital to labour increases sharply. So, statement (a) is true.
Industrialization also leads to an increase in production of goods and services (with the same amount of labour or maybe less labour). So, production per labour also increases which means an increase in labour productivity. So, statement (b) is also true.
Total factor productivity means the productivity of all factors of production i.e. labour, capital, land etc. During industrialization, since overall production increases, production per unit of inputs i.e. labour, capital, land etc also increases. So, statement (c) is also true. Productivity of labour = $\text"Output"/\text"Labour"$
Productivity of land = $\text"Output"/\text"Land"$
We all know that because of industrialization output increased. Now if output increased (with the same land and labour), then as per the above formula, productivity of land and productivity of labour, both will increase.
So, in case of industrialization, productivity of all the factors of production increases.
