Correct answer: D
Solution
(d) The cyclical activity of cambium produces annual rings. Climate conditions in temperate zones are rarely consistent throughout the year. The climatic conditions in the tropics, on the other hand, are consistent throughout the year. As a result, in temperate plants, cambium is more active in the spring and less active in the autumn.More Anatomy of Flowering Plants PYQs
