D Correct answer
Explanation

Tree age is determined by counting annual growth rings in the trunk's cross-section. Each ring represents one year of growth, with light-colored rings forming in spring and darker rings in late summer. This scientific method is called dendrochronology. Height and diameter change throughout a tree's life and don't indicate age, while sap analysis reveals health but not age.
