An amplifier has an open-loop gain of $100$, an input impedance of $1 \; \mathrm{k \Omega}$, and an output impedance of $100 \; \Omega$. A feedback network with a feedback factor of $0.99$ is connected to the amplifier in a voltage series feedback mode. The new input and output impedances, respectively, are
- $10 \; \Omega$ and $1 \; \Omega$
- $10 \; \Omega$ and $10 \; k \Omega$
- $100 \; \Omega$ and $1 \; \Omega$
- $100 \; k \Omega$ and $1 \; k\Omega$
