D Correct answer
Explanation

Trees produce one growth ring per year in their stems due to seasonal growth patterns - lighter colored early wood formed in spring and darker late wood in summer/fall. By counting these rings from the center to the bark (a method called dendrochronology), you can determine the exact age of the tree. Height and diameter vary based on species and environmental conditions, not just age.
