It is up to our government and planners to devise ways and means for the mobilisation of about ten crore workers whose families total up about forty crore men, women and children. Our agriculture is over-manned. A lesser number of agriculturists would mean more purchasing or spending power to every agriculturist. This will result in the shortage of man-power for many commodities to be produced for which there will be a new demand from a prosperous agrarian class. This shortage will be removed by surplus man-power released from agriculture as suggested above. The passage best supports the statement that:

The passage discusses the over-manning in agriculture, the need for the mobilization of surplus workers, and how shifting labor from agriculture could help meet the demand in other sectors. Here’s the analysis of the options based on the passage:

1. Option A - employment in production is more fruitful than employment in agriculture:
   • The passage does not directly discuss the comparative fruitfulness of employment in production versus agriculture. It focuses more on the issue of over-manning in agriculture and how reducing the number of agriculturists could help in other sectors.
   
   
   • This option is not strongly supported by the passage.


2. Option B - Indian economy is in a poor shape basically due to improper mobilisation of man-power:
   • The passage mentions the need to mobilize labor and the impact of surplus manpower in agriculture but does not directly state that the Indian economy is in poor shape due to improper mobilization. It focuses more on potential improvements through better mobilization rather than labeling the economy as poor.
   
   
   • This option is not fully supported by the passage.


3. Option C - a shift of labour from agricultural sector to the industrial sector would uplift the living standard:
   • The passage suggests that reducing the number of agriculturists could increase purchasing power, which could lead to a prosperous agrarian class, but it does not directly link this to an uplift in living standards through a shift of labor to the industrial sector.
   
   
   • This option is not directly supported by the passage, although it is implied indirectly.


4. Option D - the industrial sector is labour-deficient while the agricultural sector is over-manned in our country:
   • The passage directly addresses the issue of over-manning in agriculture, suggesting that reducing the number of agriculturists could free up surplus labor for other sectors. It implies that the agricultural sector is over-manned and labor could be utilized in other sectors where there is a demand for labor.
   
   
   • This option is strongly supported by the passage.


5. Final Answer:
   • The best supported statement by the passage is D. the industrial sector is labour-deficient while the agricultural sector is over-manned in our country.
