Answer:

Whether a traffic light is green, yellow or red

Explanation:

Boolean variables are variables that can either take one out of two options at any given instance.

Analyzing the given options

1. Elevator:

Possible Directions = Up or Down; That's two possible values

But it can only move in one direction at a given instance.

<em>This can be represented using Boolean</em>

2. Traffic Light:

Possible Lights = Green, Yellow or Red

That's three options.

<em>This can be represented using Boolean</em>

<em />

The last two options can be represented using Boolean because they have just two possible values

<em>Hence, option (B) answers the question</em>
