**Explanation:**

When the speed of the traffic flow becomes zero, it means that the vehicles in the traffic are not moving at all. In this situation, there is a high concentration of vehicles in a given space, which leads to a high traffic density.

**Traffic Density:**

Traffic density refers to the number of vehicles per unit length of the road. It is calculated by dividing the number of vehicles by the length of the road segment. When the speed of traffic flow becomes zero, it indicates that the vehicles are stationary, and therefore the traffic density reaches its maximum value. This is because all the vehicles are occupying the same space on the road, resulting in a high concentration of vehicles.

**Traffic Volume:**

Traffic volume refers to the number of vehicles passing through a particular point on the road in a given time period. It is calculated by multiplying the flow rate (number of vehicles per unit time) by the duration of time. When the speed of traffic flow becomes zero, it means that no vehicles are passing through the point, and therefore the traffic volume becomes zero.

**Relation between Traffic Density and Traffic Volume:**

Traffic density and traffic volume are related to each other. Traffic volume is the product of traffic density and speed. Mathematically, traffic volume (V) can be represented as V = D x S, where D is the traffic density and S is the speed of traffic flow.

When the speed of traffic flow becomes zero, the traffic volume also becomes zero, regardless of the traffic density. This is because even if the traffic density is high, there is no flow of vehicles, and hence no vehicles are passing through the point in a given time period.

**Conclusion:**

Therefore, when the speed of the traffic flow becomes zero, the traffic density attains its maximum value, indicating a high concentration of vehicles in a given space. At the same time, the traffic volume becomes zero, as no vehicles are passing through the point. Hence, option 'A' is the correct answer.
