Correct Answer: Option C
Explanation

Iron is not a primary component of duralumin, but it is the primary component of steel alloys. Duralumin is primarily an aluminum alloy, while steel is primarily an iron alloy. 

Iron is not a primary or defining component of either brass or bronze alloys; brass is primarily a copper-zinc alloy, while bronze is primarily a copper-tin alloy. 

Permalloy is a nickel–iron magnetic alloy, with about 80% nickel and 20% iron content.

Iron is generally not present in soft solder alloys, which are typically composed of tin and lead, or tin with other metals like silver or copper.
