Explanation
Why Correct: Black money is unaccounted income that primarily benefits the wealthy, widening the gap between rich and poor. This increases income inequality.
Distractor Analysis: Decrease in quality of output is not a direct or necessary consequence of black money — it can distort markets but does not inherently lower output quality. High living standard for all is false, as black money concentrates wealth, not distributes it. Both claims are therefore incorrect.
Takeaway: Black money exacerbates inequality, reduces tax revenue, and fuels corruption. It does not improve general living standards.
