Which of the following wood types is classified as a hardwood?

Hardwoods are classified based on the type of tree they come from, specifically angiosperms, which are trees that have broad leaves and produce flowers and seeds. Among the options provided, oak is a quintessential example of a hardwood. It is known for its density, strength, and durability, making it a popular choice for furniture and cabinetry in addition to its use in caskets.

While birch is also considered a hardwood, the distinction often made in funeral service is regarding the more commonly used and recognizable hardwoods for casket manufacturing, where oak stands out due to its characteristics and tradition in the industry.

In contrast, pine and cedar are classified as softwoods, derived from coniferous trees that tend to have needle-like leaves and produce cones. Softwoods are generally less dense than hardwoods and are often used in less formal applications, contributing to their classification in this context.
