Answer:

Option C (increase her consumption of carry-out lunches and decrease her consumption of magazines) is the correct answer.

Explanation:

The marginal utility offered by carryout lunches is higher than the marginal utility provided by the use of magazines in proportion to the total spending required on them respectively. Melika will be able to derive maximum utility if she increases her consumption of carry-out lunches as the loss from decrease in the consumption of magazines will be compensated by the higher use of carry-out lunches.
