This question is about a country level population policy from 2019. Three of the four options can be set aside as a group first, then the real answer can be confirmed on its own.
India, Norway and Finland all run family welfare or parental leave programmes, but in none of these countries is a woman's income tax waived for life simply because she has four children. So these three options fail on the same ground, no permanent tax exemption tied to child count exists in their policy frameworks.
Hungary is different. To fight a falling birth rate, the Hungarian government rolled out a family support package in 2019 that gave women with four or more children a lifetime exemption from personal income tax, on top of housing subsidies and preferential loans. This is a direct match for what the question describes.
So the correct answer is Hungary.
Hungary had been recording one of the lowest fertility rates in the European Union through the 2010s, and its government used its 2019 budget announcement to respond directly with a tax based incentive rather than a cash handout.
Weighing the four against the specific 2019 tax announcement, only Hungary fits.
Therefore, the correct answer is Hungary.
