The second alternative is correct (B).
Analyzing the US income breakdown for 2010, we can infer that the top 1% of the richest hold approximately 35% of total wealth, while the poorest 80% concentrate approximately 10% of total income. The other 19% concentrate just over 50% of the rent.
This shows that the US, despite being the richest country in the world, is an unequal country.
