Concept:PCB stands for Printed Circuit Board, which is the standard platform used to mechanically support and electrically connect electronic components.
Explanation:A PCB is a thin board made from a non-conductive material, usually fiberglass.
Thin copper tracks are printed or etched onto the board to form the required electrical connections.
Electronic components such as resistors, capacitors, and integrated circuits are soldered onto the board.
These copper pathways replace traditional wires, making circuits more compact, reliable, and easier to mass-produce.
Now, let us check the given options.
Option 1, "Picture Circuit Board," is not a real or recognized term in electronics.
Option 3, "Printed Control Board," suggests a board used only for control purposes, which is too specific for the general meaning of PCB.
Option 4, "Picture Control Board," is also incorrect because PCB has nothing to do with pictures or control functions.
Only Option 2 correctly defines the full form of PCB.
Answer:Option B: Printed Circuit Board
