A
. Leaves were trapped between layers of sediment millions of years ago, causing the imprint
Explanation:
The only true explanation that perfectly describes the rock is that the leaves were trapped between the layers of sediment millions of years ago causing the imprint.
Leaf imprints are often referred to as trace fossils.
- Trace fossils points to the different life activities an organism must have been engaged in.
- When a leaf is trapped in a soft sediment between two layers, the compaction of the sediment can duplicate the form of leaf on beds.
- This gives a physical overview to the nature of leaf.
- Such an imprint did not grow, and cannot be attributed to metamorphic processes(option D).
- Option C is completely wrong

Answer: Rainfall is scarce.
Explanation:
Coniferous forests are one of the coldest biomes of the world. They exhibit very low annual rainfall, short summers and hot and cold and long winters. The temperatures of the region exhibit long range. They are dominated by the vegetation cover of coniferous trees which exhibit adaptations like needles instead of leaves and cones instead of flowers which preserves seeds. The leaves and flowers are absent because of scanty rainfall and low sunlight which are necessary for photosynthesis and blooming of flowers.
