Question

If a country wants to increase its GDP, what actions could be taken?

Answer 1

If an country wants to increase its GDP, It must invest in a General Capital, and an Human capital. Once those are invested, Entrepreneurs will, come into the State/Country, and start creating an conductive environment. 
The order of GDP investing goes as is:
1. Invest In a General Capital
2. Invest In a Human Capital
3. Entrepreneurs create a conductive environment
So the answer would be all of the above :) (I have been to an country, that has had low GDP, I've seen Entrepreneurs, help the country to invest in the capitals, and then start building the Conductive Environment.) Have A Good Day!

Option D.

Explanation:

I choose this option because all the three factors are necessary to increase the nation's GDP (gross domestical product) and it is because the first option is regarding the labour force (intiated employment) and the second one is investment in all fields, as this would result in more production of goods which is added to GDP.  

The third option is about removing the barriers for the investors such as tax, legal formalities and also intiating them to participate actively by certain measures
