D Correct answer
Explanation

The age of a tree is determined by counting the annual growth rings in its trunk (dendrochronology). Each year, a tree typically produces one growth ring consisting of a light spring wood and dark summer wood. Measuring height, diameter, or sap analysis cannot provide accurate age determination, only growth rings can.
