I. for current amplification.

II. for voltage stabilization.

III. for power amplification.

IV. as a switch.

Myschool is wrong.
Transistors cannot be used for voltage stabilization
But they can be used as power amplification, current amplification, voltage amplification and can also be used as a switch.
Hence the ans is B.
NB: Transistors can be used for voltage amplification but not for voltage stabilization.
What can be used for voltage stabilization is a Zener Diode.

Voltage stabilization is not a primary function of a transistor. Transistors are mainly used for current amplification, power amplification, and as switches. While transistors can indirectly contribute to voltage stabilization in certain circuits, it's not a typical or primary application of transistors.

So the answer is B

Wrong!!
Transistor is a kind of solid semi-conductor device, which has many functions, such as detecting, rectifying, amplifying, switching, "VOLTAGE STABILIZATION", signal modulating and so on
