(B) An $n-p-n$ transistor consists of a $p$-type base sandwiched between two $n$-type regions (emitter and collector).This structure creates two $p-n$ junctions: the emitter-base junction and the collector-base junction.In an $n-p-n$ transistor,the base is $p$-type and both the emitter and collector are $n$-type.When represented as two diodes,the $p$-type base acts as the common terminal for the anodes of both diodes.Therefore,the two diodes are connected such that their anodes are joined at the base terminal $(B)$,while their cathodes point towards the emitter $(E)$ and collector $(C)$ terminals respectively.This configuration is correctly represented by two diodes with their anodes connected to the base terminal.

An $n-p-n$ transistor can be considered to be equivalent to two diodes connected back-to-back. Which of the following figures correctly represents this equivalent circuit?
