Answer:
The correct answer is Demographic segmentation by Income

In marketing Demographic segmentation implies segmentation of the market in groups by certain factors, like for example, race, age, education, income, religion, etc... to exploit the demographics in their advantage this marketing study helps to identify where would a product or service sell more, or where is convenient to open up a business.
Now in this particular case, Deal$ stores are using income segmentation by selling products of a certain (in this case lower) price, the whole attractive of Deal$ stores is the lower price and not the quality of the products sold there, thats why income segmentation is present, because they are literally aiming at one specific kind of customer that wants really low prices.
