The current amplification factor of a transistor is $50$. The input resistance when used in common emitter mode is $1 \text{ k}\Omega$. The peak value of the collector current for an a.c. input voltage of $0.01 \text{ V}$ peak is:
- A$100 \mu\text{A}$
- B$0.01 \text{ mA}$
- C$0.25 \text{ mA}$
- D$500 \mu\text{A}$
