• A. $2315$
• B. $3241$
• C. $2534$
• D. $3514$

Answer 1

Answer: (D)

$3514$

A). Astronomical telescope - Contains a convex lens of large focal length in the objective and a convex lens of small focal length in the eye-piece

B.) Galilean Telescope - Contains a convex lens of large focal length in the objective and a concave lens of small focal length in the eye-piece

C). Simple Microscope - Contains one convex lens

D.) Compound Microscope - Contains a convex lens of small focal length in the objective and a convex lens of large focal length in the eye-piece

Thus,

A - 3 , B - 5 , C - 1 and D - 4 , hence Option D is correct.
