Question

Match the following:

List-I (Sol)	List-II (Method of preparation)
A) \( \text{As}_2\text{S}_3 \)	I) Bredig's arc method
B) \( \text{Au} \)	II) Oxidation
C) \( \text{S} \)	III) Hydrolysis
D) \( \text{Fe(OH)}_3 \)	IV) Double decomposition

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

Hint:

In matching-type questions, carefully analyze each compound's preparation method. Double-check common methods of preparation for accuracy.
