Since there is no feedback hence it is internal gain.

As there is no feedback in open loop circuit we can say that it's voltage gain will be internal only on dependent upon it's input voltage.

Dude can you explain me what is open-loop voltage gain?

As we know the defination voltage gain is output to input voltage gain.. Here also same but diffrence is op-amp. In this there is no feedback for the op-amp circuit.

In other words open loop voltage of an op amp is the maximum gain gain that the op amp can give (i.e. If the parameters are unchanged since once an op amp is manufactured it can not changed it is also called internal voltage gain) and using a feedback resistor loop we decrease our gain.

There is no feed in open loop voltage gain so the internal voltage is the answer.

Open loop voltage gain of opamp is that where there is no feedback path.
