Given below are two statements:
Statement-I: In the fixed-bias configuration of an n-p-n, BJT operating in the active regime, the magnitude of collector current does not depend on $R_c.$ (See the figure)
Statement-II: In the fixed-bus configuration shown in figure, base current is controlled by $R_B$. 
In the light of the above statements, choose the correct answer from the options given below.

Given below are two statements, one is labelled as Assertion (A) and the other is labelled as Reason (R):
Assertion (A): Emitter-follower configuration of BJT is used for impedance- matching applications.
Reason (R) : In a common-collector configuration of BJT, the output voltage at the emitter is in phase with input signal. 
In the light of the above statements, choose the correct answer from the options given below.
