The correct statement regarding the differences between light microscopes and electron microscopes is:

d. Light microscopes can examine living specimens; electron microscopes cannot.

Here’s a brief explanation of the key differences:

  • Light Microscopes: Use visible light and lenses to magnify specimens. They can typically magnify up to about 1,000 to 1,500 times and can be used to observe living organisms or cells.

  • Electron Microscopes: Use beams of electrons instead of light to achieve much higher magnifications, typically up to 100,000 times or more. However, because the samples often require a vacuum and can be damaged by the electron beam, electron microscopes cannot be used to view living specimens.

The other statements contain inaccuracies regarding the capabilities and usage of light and electron microscopes.
