[amp_mcq option1=”traffic density attains maximum value whereas traffic volume becomes zero” option2=”traffic density and traffic volume both attain maximum value” option3=”traffic density and traffic volume both become zero” option4=”traffic density becomes zero whereas traffic volume attains maximum value” correct=”option3″]<\/p>\n
The correct answer is: C. traffic density and traffic volume both become zero.<\/p>\n
When the speed of traffic flow becomes zero, it means that the vehicles are not moving. This can happen for a number of reasons, such as a traffic jam, an accident, or a road closure. When the vehicles are not moving, there is no traffic flow and therefore no traffic density or traffic volume.<\/p>\n
Option A is incorrect because traffic density cannot attain a maximum value when there is no traffic flow. Option B is incorrect because traffic volume cannot attain a maximum value when there is no traffic flow. Option D is incorrect because traffic density cannot become zero when there are vehicles present.<\/p>\n","protected":false},"excerpt":{"rendered":"
