Would current flow through MOSFET if its source pin and gate pin are connected? as shown in picture. correct answer will get brillientist and Spam answer will be reported...

Answer:
The intrinsic body diode inside the MOSFET is in parallel with the conduction channel, however. When the conduction channel is present, the diode is shunted and current flows through the path of least resistance (the channel). When the channel is off, the diode is in circuit and will either conduct or block depending on the drain-source current polarity.
As your picture shows, there are both N-channel and P-channel devices, as well as enhancement mode and depletion mode devices. In all of these cases, current can flow from source to drain as well as from drain to source - it's just a matter of how the device is connected in the circuit.
Your picture does not show the intrinsic diode in the devices - the arrow point towards or away from the gate is an indication of the channel type (N-channel points towards the gate, P-channel points away from the gate).
