ANS:A - brass

Dezincification is a form of corrosion especially applicable to brass. Brass is an alloy primarily composed of copper and zinc. Dezincification is a type of corrosion that occurs in brass when the zinc component of the alloy is selectively removed from the material, leaving behind a porous copper structure. This process weakens the material and can lead to structural failure, particularly in applications where the brass is exposed to aggressive environments containing oxygen, moisture, and certain impurities. Nichrome is a nickel-chromium alloy, stainless steel is an iron-chromium alloy with nickel, and Monel is a nickel-copper alloy. While these materials can also experience corrosion under certain conditions, dezincification specifically pertains to brass due to the selective removal of zinc from the alloy during corrosion processes.
