Correct option is C)

When Zener diode is forward biased, it behaves like ordinary diode and when reverse biased, it will be a voltage stabilizer. Also, at room temperature, the voltage across the depletion layer for silicon is about and for germanium is about  
Hence, statement 
A is correct but statement B is wrong.
