Transfer payments are payments made from the government to individuals or other entities without any goods or services being exchanged. They are used to redistribute income and provide assistance to specific groups of people. In this question, we are asked to identify examples of transfer payments.

Option 1: Unemployment Allowance. This is an example of a transfer payment because it is a payment made by the government to individuals who are unemployed, without any goods or services being exchanged.

Option 2: Payment of Salary. This is not an example of a transfer payment because it involves the exchange of goods or services. A salary is given in exchange for work or services provided.

Option 3: Social Security Payments and Old age Pension. These are both examples of transfer payments. Social security payments are made by the government to provide financial assistance to individuals who are retired, disabled, or surviving family members of deceased workers. Old age pension is a transfer payment made to elderly individuals to support their living expenses.

Option 4: None of the above. This option is incorrect because options 1, 3, and 4 are all examples of transfer payments. Therefore, the correct answer is option 3.
