Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Soldering is a process used to join metal components together by melting a filler metal (solder) into the joint.
The most commonly used solder in traditional electronics is an alloy of tin (Sn) and lead (Pb).
A typical composition is 60% tin and 40% lead.
Tin provides good wetting properties while lead lowers the melting point, making it ideal for electronic applications.
Other materials like copper, aluminium, and nickel are base metals and are not used as the main soldering material.
