The answer is C. Pocket money.
Wages, honorarium, and salary are all forms of payment for work done. Pocket money is not a form of payment for work done, but rather an allowance given to children or teenagers by their parents or guardians.
Wages are a fixed amount of money paid to an employee for each hour or day of work. Honorarium is a payment made for services rendered, but which is not considered to be a salary or wage. Salary is a fixed amount of money paid to an employee on a regular basis, usually monthly or biweekly.
Pocket money is typically given to children or teenagers to spend on whatever they want. It is not considered to be a form of payment for work done, and it is not usually subject to taxes.
