Q1:

Age of a tree may be ascertained by

B circumference of its stem

C number of branches

D number of annual rings.

If you know when the tree was planted, you can easily and accurately determine its age. The second most accurate way to estimate tree age is to count the annual rings of wood growth. Annual rings can be counted using two different methods. You can extract an increment core from the tree using an increment borer.
