A change of $$0.04 \mathrm{~V}$$ takes place between the base and the emitter when an input signal is connected to the common emitter transistor amplifier. As a result, $$20 ~\mu \mathrm{A}$$ change takes place in the base current and a change of $$2 \mathrm{~mA}$$ takes place in the collector current. The input resistance and AC current gain are

A
$$1 \mathrm{~k} \Omega$$ and 100
B
$$2 \mathrm{~k} \Omega$$ and 100
C
$$2 \mathrm{~k} \Omega$$ and 1000
D
