Solution
The correct option is B
the collector is positive and the emitter is negative with respect to the base.
The NPN transistor is made of semiconductor materials like silicon or germanium. When a p-type semiconductor material is fused between two n-type semiconductor materials, an NPN transistor is formed.
An NPN transistor conducts when the collector is positive and the emitter is negative with respect to the base because the emitter-base junction is forward bias and the collector-base junction is reverse bias.
Hence, the answer is (B) the collector is positive and the emitter is negative with respect to the base.
