Pension is the regular sum that an employee receives after retirement.
After the death of the employee, in many cases, the pension is passed on to their spouse or children. This pension is a family pension.

Arjun passes after 3 years, his pension amount will be now transferred to his wife, this is called family pension. His wife needs to file ITR 1 and show the family pension income under the head income from Other Sources.
