• B. (A)-(III), (B)-(II), (C)-(I), (D)-(IV)
• C. (A)-(III), (B)-(II), (C)-(IV), (D)-(I)
• D. (A)-(II), (B)-(IV), (C)-(I), (D)-(III)

Answer 1

Answer: (B)

(A)-(III), (B)-(II), (C)-(I), (D)-(IV)

Answer 2

Matching the optical instruments with the correct types of lenses/mirrors:-
- Human Eye (A) → (III) Lens of adjustable focal length,
- Microscope(B) → (II) Objective lens of large aperture and large focal length,
- Reflecting Telescope (C) → (I) Concave mirror of large aperture and large focal length,
- Refracting Telescope (D) → (IV) Objective of small aperture and small focal length.
Thus, the correct match is Option (2).
