Urban Planner: The installation of green roofs in urban areas can reduce the overall city temperature during summer months, thereby reducing the need for air conditioning and energy consumption. However, despite their benefits, the widespread adoption of green roofs has been slow. This is because the initial cost of installing green roofs is considerably high, and because __________.
Which of the following, if true, most logically completes the urban planner’s argument?
(A) there are sufficient numbers of skilled laborers available to install green roofs
(B) green roof materials are often sourced from suppliers who are located far from urban centers
(C) tax incentives for green construction projects are commonly available in urban areas
(D) traditional roofing solutions are generally less expensive and quicker to install than green roofs
(E) green roofs typically last longer than traditional roofing materials, thus potentially saving money over time

(C) - tax incentives would encourage people to adopt green roofs fast, hence, not the appropriate statement here
(D) - In comparison to traditional roofing solutions, green roofs are more expensive, and slower to install, hence the rate of adoption is slower.(E) - similar reasoning to (A)
