a. needs.
b. limits.
c. needs and wants.
d. wants and limits.

Answer 1

I will chose letter c. needs and wants.  When you look at what she is paying for. It is a combination of needs and wants.  The needs are grocery and water while the wants are cable and cellphone bills.  So she has to make a choice which of these will be her priorities.

Answer 2

The correct option is C.
Human needs refers to those items that are very essential for survival, one can not possibly do without them, if the needs are not met it will lead to negative consequences. Human wants on the other hand refer to those items that we desire whether now or in the future. Human wants differ, it depends on individual's taste. Examples of need are water, food, air and shelter. 
In the question given above, water and grocery are needs while cable and cell phone are wants.
