Which tree is described as having high pollution tolerance?

• A. Ginkgo bilboa
• B. Galls
• C. Juneberry
• D. Birch tree

Answer: (A)

Urban pollution tolerance is a key factor when choosing trees for city streets. Ginkgo has long been valued for surviving heavy air pollution, road salt, drought, and compacted soils. Its hardy, resilient vascular system lets it stay healthy where many other trees struggle, making it a reliable urban survivor. That’s why it’s commonly planted along polluted streets and in city canyons. In contrast, juneberry and birch don’t withstand urban pollutants as readily, and the option that isn’t a tree isn’t a candidate for this trait. So the tree described as having high pollution tolerance is the ginkgo.
