Yeah. It may be 3 or 4. According to the design requirements we will take 3 or 4.
4th terminal is substrate terminal.
If Vsb=0 ---3.
If Vsb not equal to zero then 4terminals. That means if sourcr and substrate has different potential then two different terminals will be taken.

The MOSFET (Metal Oxide Semiconductor Field Effect Transistor) transistor is a semiconductor device which is widely used for switching and amplifying electronic signals in the electronic devices. The MOSFET is a three terminal device such as source, gate, and drain.

I Think answer 3 or 4 is right beacuse in option this is available and we know that in MOSFET substrate is also a terminal otherwise it is internally built in it thats why we say that MOSTET has three terminal.

Substrate is of either p type or n type like source & drain know, I think we are not taken into account the substrate.

The terminals are;
- Gate
- Source
- Drain
- Bulk
*Bulk may be present or not depending on the application.

If Vsb(source to body voltage) = 0. Then 3 terminal.
If Vsb(source to body voltage) ≠ 0. Then 4 terminal.
If Vsb(source to body voltage) ≠ 0. Then 4 terminal.

GATE, SOURCE, DRAIN AND SUBSTRATE, In some cases the substrate internally connected to the source.

MOSFET has only 3 terminal namely source, drain &gate.please answer me name of 4th terminal.

Substrate is not terminal it is material (sio2) etc. So answer is only 3 terminal.

Each MOSFET has 4 terminals called body (B), source (S), gate (G) and drain (D).
