The amplifier circuit shown below uses a silicon transistor. The capacitors $\mathrm{C}_{\mathrm{C}}$ and $\mathrm{C}_{\mathrm{E}}$ can be assumed to be short at signal frequency and the effect of output resistance $\tau_O$ can be ignored. If $C_{E}$ is disconnected from the circuit, which one of the following statements is $\text{TRUE?}$

1. The input resistance $R_i$ increases and the magnitude of voltage gain $A_v$ decreases
2. The input resistance $R_i$ decreases and the magnitude of voltage gain $A_v$ increases
3. Both input resistance $R_i$ and the magnitude of voltage gain $A_v$ decrease
4. Both input resistance $R_i$ and the magnitude of voltage gain $A_{v}$ increase
