Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

According to the question option A is correct because the person is buying a new house for self occupation and through this occupation whatever he will earn will be added to the national income of a country hence it is indirectly associated to the contribution of national income and according to option (d) the person bought the car for self use it will not generate any kind of income to the person because he is using the car for his needs in case the option will be buying new car for transportation or taxi services then it will be included for national income... i hope I have cleared your doubt
