Please explain me the ans.

Whenever a neg(-) sign apply at base and Vcc at collector then transistor is switched on and voltage appear at output.
E.g. (Vce=Vcc-IR)
E.g. (Vce=Vcc-IR)

One logic is there here basically at high resistance tr does not conduct. I/p resistance is in mega-ohm.

Here transistor is forward bias so total voltage is going to the ground so output voltage will be zero.

In this figure the voltage at base terminal is enough to switch on transistor, and if its on the voltage across Vce=0v and Vce=Vout=0v.

Vce=Vcc-Ic*Rc.
When the tr. conduct(due to positive I/P or base-emitter voltage here CE config. ) the collector current increases and voltage drop across Rc increases which in turns decreases Vce bcz Vcc is fixed. That's why when input voltage is high then output voltage Vce is 0 i.e 0v.

I think this transistor is used here as switching. So the current goes towards ground. So op is 0.

It is because Rb is 1 megaohms, no current will pass through.

That circuit is an inverter circuit. So, when the input voltage is HIGH, the output voltage will be LOW. That's why the answer is 0V.
