A transistor connected in common base configuration has:a)A high input...
Input Terminal Emitter – Base (EB)
Output Terminal Collector – Base (CB)
Since for Amplification Application in BJT
EB Junction → Forward Biased (Low Impedance)
CB Junction → Reversed Biased (High Impedance)
Input Impedance is low
Output Impedance is high

Common Base Configuration
The common base configuration is one of the three basic transistor configurations. In this configuration, the base terminal of the transistor is common between the input and output circuits, while the emitter is the input terminal and the collector is the output terminal.
Input Resistance
The input resistance of a circuit is the resistance that the circuit presents to the input signal. In the common base configuration, the input resistance is low because the emitter is connected directly to the input signal. This means that the input signal can easily drive the transistor.
Output Resistance
The output resistance of a circuit is the resistance that the circuit presents to the output signal. In the common base configuration, the output resistance is high because the collector is connected to the load resistor. This means that the output signal has to overcome the load resistor before it can be delivered to the load.
Answer
Thus, the correct answer is option 'C': a transistor connected in common base configuration has a low input resistance and high output resistance.
