Final Answer:
One advantage of light microscopes over electron microscopes is their lower cost. Option A) is the answer.
Step-by-step explanation:
Light microscopes use visible light to magnify specimens, while electron microscopes utilize electron beams. Although electron microscopes offer higher resolution and greater magnification, they come with a significantly higher cost compared to light microscopes. Light microscopes are more accessible to a broader range of users, including educational institutions and smaller research facilities with budget constraints. The lower cost of light microscopes makes them a practical choice for routine laboratory use and introductory educational purposes, providing a balance between affordability and sufficient magnification capabilities.
Option A (Lower cost) is the answer.
