Wood water towers are unique because wood is a material that expands when wet, helping to prevent leaks. This characteristic of wood makes it an ideal material for water towers since it can adapt to changes in moisture levels, reducing the likelihood of leaks. Additionally, wood water towers are generally cheaper to build and maintain compared to steel water towers. The fact that water freezes later in wood than in steel further highlights the advantages of using wood for water towers in regions with colder climates like New York City. This combination of properties makes the use of wood a practical and efficient choice for water towers, making option D the correct answer.
