The resolution of an electron microscope is much higher than that of the human eye or a conventional light microscope due to the very short (nanometer) wavelengths of electrons. This is the primary reason.

However, all the options mentioned contribute to the superior resolution of an electron microscope.

1. Very short (nanometer) wavelengths of electrons: Shorter wavelengths allow the microscope to resolve smaller structures, providing a detailed image.

2. Higher magnification: Electron microscopes can magnify objects up to 50 million times, while light microscopes can only magnify up to 2000 times. This higher magnification allows for a more detailed view of the specimen.

3. Quality of lenses: The lenses used in electron microscopes are of high quality and are designed to control the electron beam accurately, contributing to the high resolution.

So, the answer is "All of the answers".
