In reverse bias diode act like this, is its normal behavior nothing wrong with diode.

When diode is connected in reverse bias, it shows high impedance because it acts like an open circuit.

The diode is not any bias since we are not providing any energy source, but when the configuration of the circuit is like this it will show the reverse bias resistance of the diode which may be infinity (ideal) or may be a very high value (for the practical diode) in mega-ohm range. So option C is correct.

Since, there is no source to ON the diode, then there is no current.

Nothing, because no supply is given to diode so how decided it will go into reverse or forward biased. So, option C is right.

Ideal diode has no resistance then how it's possible.
And in RB Ideal diode must be infinite resistance.
And in RB Ideal diode must be infinite resistance.
