Answer:
a. 1/3
Explanation:
Although, this is a controversial topic and it is hard to state exactly how much income share the top 1% or how much of the United State's wealth rests with the wealthiest top 1% but, it can be said that approximately one-third (1/3) of the wealth remains with the top 1%. Also, some of the sources like Washington Post suggests that up to 40% of the wealth rests with the US top 1% households. Hence, given the options, 1/3 is most suitable.
