Which of the following device should be used as a switch in a low power switched mode power supply (SMPS)? Correct Answer MOSFET

MOSFET has a low power rating and high-frequency rating and so it can be used in low power switch mode power supply. MOSFET stands for metal oxide silicon field effect transistor.

S1: This is the story of a tram that woke up at dead of night and went off on a trip all by itself to end in a disaster.
P: In the early morning of 19 January it suddenly started backing out of the depot on its own.
Q: Tramways sources explained that power supply to the overhead wires at the siding had been switched off for some repair work.
R: It went up a quarter mile away, crashed into state bus which caught fire went it smashed into an electric feeder box and a water tap.
S: There was presumably, some defect in the reversal handle of the tram and its main switch had not been put off.
S6: As a result, when the power supply was restored in the early morning the tram began to move.

The Proper sequence should be:
