Which of the following trees is most suitable for pulp and paper production?

Spruce is the most suitable tree for pulp and paper production. This is because spruce wood has long fibers and a high cellulose content, which are both important properties for making paper products. Additionally, spruce wood has a relatively low lignin content, which makes it easier to pulp and process into paper. Obeche, ebony, and mahogany are all hardwood trees, and while they may have desirable properties such as durability and strength, they are not typically used for paper production due to their low fiber content and high lignin content.
