People of this country have been finding it difficult to buy their own

People of this country have been finding it difficult to buy their own houses. In the last two decades, the percentage of working population possessing their own homes has gone down. The primary reason is that while the average salary of the working population has increased fivefold in the last two decades, the average cost of a house has shot up ten times. Clearly, the government has not done enough to ensure that the citizens' salaries increase as per the increasing costs of houses.

Which of the following, if true, would most weaken the argument above?

A. In the two decades before the last two, the disparity between salary and housing prices was rising too.
B. The trend of rental accommodation has increased drastically in the last two decades, adding to the financial benefits of owning a house and thereby, increasing the cost of owning a house.
C. Most immigrants who entered the country in the last two decades have purchased their own houses.
D. The percentage of working people owning their own houses has declined more rapidly in the last decade than in the decade preceding this last.
E. The number of jobs in the country has gone up by fifty percent while the number of houses has gone up by forty percent in the last two decades.
