Three terminals of a transistor,denoted by $P, Q,$ and $R,$ are tested using a multimeter. No conduction occurs between $P$ and $Q.$ When the negative lead of the multimeter is connected to $R$ and the positive lead is connected to either $P$ or $Q,$ the meter shows some resistance. Which of the following options is correct for the given transistor?
- AIt is an $N-P-N$ transistor and $R$ is the collector.
- BIt is an $N-P-N$ transistor and $R$ is the base.
- CIt is a $P-N-P$ transistor and $R$ is the collector.
- DIt is a $P-N-P$ transistor and $R$ is the base.
