As a finance analyst, you need to calculate the tax owed by individuals based on their income, tax bracket, and marital status, considering deductions for specific expenses. Write a Python program that calculates the tax for a given income, tax bracket, and marital status, taking into account the following:

Deduction for medical expenses: Individuals can deduct $5\%$ of their annual income for medical expenses.

Deduction for education expenses: Individuals can deduct $2\%$ of their annual income for education expenses.

Introduce the following changes to the tax brackets based on marital status:

Bracket A: Income up to $50,000$ US dollars is taxed at $10\%$ for unmarried and $8\%$ for married.

Bracket B: Income from $50,001$ to $100,000$ US dollars is taxed at $20\%$ for unmarried and $18\%$ for married.

Bracket C: Income above $100,000$ US dollars is taxed at $30\%$ for unmarried and $28\%$ for married.

Your program should now consider these changes in tax brackets, marital status, and deductions to calculate and output the final amount of tax owed based on the given income, tax bracket, and marital status.
