When the EB junction of a transistor is reverse biased then collector ...

When the emitter-base (EB) junction of a transistor is reverse-biased, the collector current typically becomes very small or approaches zero. Therefore, the correct answer is 1
Concept:

In a normal operating condition, when the emitter-base junction of a transistor is forward-biased, it allows current to flow from the emitter to the base. This forward biasing establishes the necessary conditions for the transistor to function as an amplifier or switch.
However, when the emitter-base junction is reverse-biased (reverse voltage applied), the depletion region of the junction widens, making it difficult for the majority carriers to cross the junction. As a result, the flow of current from the collector to the emitter is significantly reduced.
In this reverse-biased condition, only a small amount of leakage current may flow through the junction due to minority carriers (minority carrier leakage), but the collector current is typically negligible or considered close to zero.
