Concept:
Microscopes are instruments used to observe very small objects that cannot be seen clearly with the naked eye.
Step 1: Identify microscope using visible light.
A light microscope uses visible light and lenses to magnify specimens.
\[
\text{Visible light} \rightarrow \text{Light microscope}
\]
Step 2: Compare with electron microscope.
An electron microscope uses a beam of electrons, not visible light.
Step 3: Final answer.
Therefore, the microscope that uses visible light is the light microscope.
\[
\therefore \text{Correct Answer is (A)}
