Model Answer
(C) Brass and Bronze
Zinc dissolved in molten copper gives brass, and tin dissolved in molten copper gives bronze.
Explanation
The question tests knowledge of common copper-based alloys. Remember: Brass = Copper + Zinc; Bronze = Copper + Tin. The order in the question is zinc first, then tin — so the answer must be Brass first, then Bronze, making (C) correct. Solder is an alloy of lead and tin, not copper-based.
