For transistor action:
$(1)$ Base,emitter and collector regions should have similar size and doping concentrations.
$(2)$ The base region must be very thin and lightly doped.
$(3)$ The emitter-base junction is forward biased and base-collector junction is reverse biased.
$(4)$ Both the emitter-base junction as well as the base-collector junction are forward biased.
Which one of the following pairs of statements is correct?

• A
  $(4)$ and $(1)$
• B
  $(1)$ and $(2)$
• C
  $(2)$ and $(3)$
• D
  $(3)$ and $(4)$
