• B. Temperate areas
• C. Tropics
• D. Near sea beaches

Answer 1

The correct option is B Temperate areas

Growth rings or annual rings are tree rings found in a cross section of a tree trunk. These rings are the result of new growth that takes place in the vascular cambium by the lateral meristems. This growth in diameter is the secondary growth and the visible rings represent the change in growth speed through the year, giving rise to concentric rings of summer wood and spring wood. The rings are more visible in the trees of the temperate zones and mark one ring per year, thus these are known as annual rings.

Thus, the correct answer is option B.
