Which of the following best describes a progressive tax system?

A progressive tax system is designed to place a higher tax burden on individuals or entities with greater ability to pay. As income increases, so does the tax rate. This system aims to promote economic equity and reduce income inequality. • For example, India follows a progressive slab system under the Income-tax Act, 1961, where taxpayers are grouped into slabs and taxed at increasing rates (e.g., 5%, 10%, 20%, 30%) based on income levels. Options A and D describe proportional (flat) taxation. Option C partially describes exemptions, not the system itself. Option E refers to corporate taxation, not progressivity.
