Concept:PCB stands for Printed Circuit Board.
Explanation:A Printed Circuit Board is a flat board made from a non-conductive material, usually fiberglass.
Thin copper tracks are etched onto its surface to connect different electronic components.
Components like resistors, capacitors, transistors, and integrated circuits are mounted on the board.
These components are soldered onto the board to make stable and reliable electrical connections.
The copper tracks act like wires, allowing electric current to flow between components.
PCB helps in reducing the size of electronic devices and makes mass production easier.
It is widely used in computers, smartphones, televisions, medical equipment, and many other electronic devices.
Among the given options, Printed Circuit Board is the correct full form of PCB.
Answer:Option B — Printed Circuit Board.
