Assertion (A) is true because direct taxes are taxes levied on individuals and companies based on their income and profits, such as income tax and corporate tax.
Reason (R) is also true because direct taxes, by nature, are paid directly by the entity on which they are imposed, and this burden cannot be shifted to others. For instance, an individual cannot pass on the income tax liability to another person. Therefore, Reason (R) correctly explains Assertion (A).
