|---|---|---|---|
| A | Turret in a microscope टरेट | I | Lever beneath the opening in the stage consists of a shutter-like group of metal leaves which regulate the amount of light coming through the slide on the stage स्टेज के छिद्र के नीचे का लीवर जिसमें धातु की पत्तियों का एक समूह होता है जो स्टेज पर स्लाइड से होकर आने वाले प्रकाश की मात्रा को नियंत्रित करता है |
| B | Condenser in a microscope कंडेनसर | II | Revolving plate which bears the objective lens, attached at the lower end of the tube; can be turned to change the objective lens घूमने वाली प्लेट जो अभिदृश्यक लेंस धारण करती है, ट्यूब के निचले सिरे से जुड़ी होती है जिसे लेंस बदलने के लिए घुमाया जा सकता है |
| C | Arm of a microscope सूक्ष्मदर्शी की भुजा | III | Short metal tube that contains a lens that fits into the top of the tube छोटी धातु की नली जिसमें एक लेंस होता है जो ट्यूब के शीर्ष पर फिट होता है |
| D | Ocular lens ऑक्युलर लेंस (नेत्रिका लेंस) | IV | Nearly C-shaped pillar arising from the base that supports the stage and ocular components आधार से उठने वाला लगभग C-आकार का स्तंभ जो स्टेज और ऑक्युलर घटकों को सहारा देता है |

Components of Compound Microscope:
- Turret (Revolving nosepiece): The rotating disc at the base of the body tube that holds the objective lenses ($10\times, 40\times, 100\times$) and allows them to be revolved into position $\rightarrow$ (II).
- Condenser / Iris Diaphragm assembly: Located beneath the stage opening, fitted with an iris diaphragm consisting of overlapping metal leaves to adjust light intensity and cone angle reaching the specimen $\rightarrow$ (I).
- Arm: The curved, C-shaped vertical metal backbone connecting the base to the body tube, providing mechanical support for the stage, focus knobs, and optical head $\rightarrow$ (IV).
- Ocular lens (Eyepiece): The upper optical cylinder inserted into the top of the body tube, which magnifies the primary image formed by the objective $\rightarrow$ (III).
Matching sequence: (A) - (II), (B) - (I), (C) - (IV), (D) - (III).
Correct Answer: Option 2.
