Which of the following is an example of a softwood?

Pine is categorized as a softwood because it comes from coniferous trees, which are typically evergreen and have needle-like leaves. Softwoods are generally known for being less dense than hardwoods, which come from deciduous trees that lose their leaves seasonally. Pine wood is widely used in construction and furniture making due to its relatively lighter weight, ease of handling, and cost-effectiveness.

In contrast, the other options—oak, maple, and birch—are examples of hardwoods. These trees typically have broader leaves and tend to produce wood that is denser and more durable, making them suitable for different purposes, such as high-quality furniture and flooring. The distinction between hardwoods and softwoods is important in understanding the properties and uses of various types of timber.
