Option D

Step-by-step explanation:

Lets analyze each of the options one at a time.

a. 43% is 40% more than Sam needs.

Wrong, because he needs as many consumers as possible.

b. Only 57% of the home owners need to build a swimming pool.

Wrong,  His business is pool cleaning, and has nothing to do with building.

c. 43% of homes with a pool means 15,586 guaranteed customers, creating a solid customer base.

Possible, but he is not guaranteed a customer just because they could use the service. This is a possible answer if there is no better answer.

d. Since pools are not often removed from a property, 43% of homes with a pool means a strong potential customer base now, with the existing home owners, and later, with new home owners.

Best answer. It is similar to option c, but with a key difference of the words potential customer base. It also logically makes sense.
