BJT :

Region of operation 

Region of operation Emitter - base Junction  Collector Base Junction 
     Cut - Off            RB             RB
    Saturation            FB             FB
       Active            FB             RB

 

When emitter base junction is reverse biased then BJT is in cutoff which means open circuited .

Collector current becomes zero.

Hence correct option is "1"
