With Proposition 13, if you bought your house 11 years ago for $75,000, your property tax would be approximately $914 a year (1 percent of $75,000 increased by 2 percent each year for 11 years); and if your neighbor bought an identical house next door to you for $200,000 this year, his tax would be $2,000 (1 percent of $200,000). Without Proposition 13, both you and your neighbor would pay $6,000 a year in property taxes (3 percent of $200,000). Which of the following is the conclusion for which the author most likely is arguing in the passage above?

(A) Proposition 13 is unconstitutional because it imposes an unequal tax on properties of equal value.

(B) If Proposition 13 is repealed, every homeowner is likely to experience a substantial increase in property taxes.

(C) By preventing inflation from driving up property values, Proposition 13 has saved homeowners thousands of dollars in property taxes.

(D) If Proposition 13 is not repealed, identical properties will continue to be taxed at different rates.

(E) Proposition 13 has benefited some homeowners more than others.

I selected the answer D but that is wrong

Reason - With Proposition 13 -

Old property wil be taxed 1% in 1st year and 2nd year 3%, 3rd year 5% and so on so in 11th year the tax will be 21% of 75000

whereas new property will be charged 1% of 200,000 in 1st year and 3% in 2nd year and so on

Now because both the properties are neighboring properties... hence thy will continue to charge differently if Proposition 13 is there

What is wrong with above reasoning?

Please explain your option and guidance on how to tackle such questions will be great
