Question

Match List-I with List-II.

List - I		List - II
A.	Sol-gel Method	I.	Top-down approach
B.	Ball Milling	II.	Thin film by rotation
C.	Chemical Vapour Deposition	III.	Bottom-up wet chemical method
D.	Spin Coating	IV.	Film growth from vapour phase

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

Hint:

Sol-gel is bottom-up, ball milling is top-down, CVD uses vapour phase, and spin coating uses rotation.
