Choose the word which is different from the rest.

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.
