What type of tree does not lose its leaves over winter?

The answer is correct because evergreen trees are characterized by their ability to maintain their foliage throughout the winter months. Unlike deciduous trees, which shed their leaves in response to changing seasons as a strategy to conserve water and energy, evergreens adapt to cold environments by keeping their needle-like leaves. These leaves are often tougher and coated with a waxy substance that helps reduce water loss, making them well-suited for survival in winter conditions.

Coniferous trees, which are often evergreen, also fall into this category because they have needle-like leaves that contribute to their ability to retain foliage during winter. Broadleaf trees, classified separately from coniferous trees, typically refer to deciduous trees and do not retain their leaves over the winter season. Thus, evergreen trees are specifically defined by their ability to remain green and leafy all year round, which is why this option is the most fitting response.
