What instrument is used to magnify or enlarge objects for viewing?

The correct choice is the microscope, as it is specifically designed for magnifying tiny objects and allows for detailed observation of structures that are too small to be seen with the naked eye. Microscopes are commonly used in various scientific fields, including biology and medicine, to examine microorganisms, cells, and other small specimens. They utilize lenses to achieve higher magnification levels, enabling users to view intricate details and make critical observations that assist in research and diagnostics.

While telescopes, magnifiers, and endoscopes also serve magnification purposes, they are designed for different applications. Telescopes are primarily used for astronomical observations to view distant celestial bodies, magnifiers are typically handheld lenses meant for enlarging text or small details for convenience, and endoscopes are specialized instruments used in medical procedures to view inside the body. Each tool has its unique function and specific context for usage, but the microscope stands out as the key instrument for deep exploration of minute objects.
