Which part forms the structural support and connects the base to the head?

• A. Arm of Microscope
• B. Ocular Lens of Microscope
• C. Stage of Microscope
• D. Lamp of Microscope

Answer: (A)

The main idea here is the structural framework of a microscope. The part that forms the structural support and connects the base to the head is the arm. It provides the rigid link between the base, which sits on the lab bench, and the head that holds the lenses. This connection helps keep the optical components aligned and stable during viewing, and the arm is also what you hold to carry the microscope. The ocular lens (eyepiece) is part of the optical path you look through, not the frame that supports the instrument. The stage is the platform where the slide sits; it moves to position the specimen under the objective lenses but doesn’t serve as the main structural connector. The lamp provides illumination for viewing but is a light source, not the structural support.
