If income increases and unnecessary expenses also increase which financial skill is necessary?

Correct answer: Expense control and saving goal

The direct answer is A: expense control and a saving goal. When income rises, a person may feel able to spend more, but unnecessary spending can rise just as quickly. Financial skill means planning where money should go before spending it. First note the income, then separate needs from wants, set a limit for optional expenses, record actual spending, and reserve a fixed amount for savings or emergencies. Option A works because it combines control with a clear future purpose. B is wrong because increasing every expense can waste the extra income and create financial stress. C is wrong because stopping records hides spending and makes poor habits difficult to notice. D is not the best answer because borrowing adds a liability when the problem is uncontrolled spending; a loan may sometimes be necessary, but it is not the basic skill required here. Remember: higher income should increase saving and planning, not automatically increase lifestyle spending. The supplied answer is financially sound.
