Elevated temperature can enhance staining quality by increasing the rate of diffusion of stains into the tissue, which can lead to more vivid and intense staining results. The increased kinetic energy at higher temperatures can facilitate the interaction of dyes with the tissue components, making certain cellular structures more visible under a microscope.

However, it is important to recognize that while a moderate increase in temperature can improve staining quality, excessive heat can lead to the formation of artifacts. Artifacts are unwanted alterations or structures that can obscure or mimic the actual histological features of the tissue. For example, high temperatures may denature proteins or alter cellular morphology, resulting in misleading or false staining patterns.

Therefore, understanding the balance between temperature and staining technique is crucial for obtaining optimal results. This dual impact of temperature illustrates why option B recognizes both the potential for improved staining and the risk of artifacts if temperatures are excessively high.
