Which of the following statements is/are true for a $\text{BJT}$ with respect to its DC current gain $\beta$ ?
- Under high-level injection condition in forward active mode, $\beta$ will decrease with increase in the magnitude of collector current.
- Under low-level injection condition in forward active mode, where the current at the emitter-base junction is dominated by recombination-generation process, $\beta$ will decrease with increase in the magnitude of collector current.
- $\beta$ will be lower when the BJT is in saturation region compared to when it is in active region.
- A higher value of $\beta$ will lead to a lower value of the collector-to-emitter breakdown voltage.
