Read the given statements carefully and answer the question :
The main reason for vehicles crawling on city roads during peak hours are increasing number of private vehicles and double parking which is a very common sight. A survey reveals that vehicles move on an average at 20 kmph during peak hours.
Which of the following is true according to the given statements?

Lets check by options:

The passage mentions double parking is a "common sight" but does not state whether it is allowed or a violation. (False)

The passage only discusses an increase in private vehicles, not government vehicles. (False)​

The passage states the average speed is 20 kmph during peak hours, but it does not specify the exact time (e.g., 5 pm to 9 pm). (False)​

The statement explicitly states that the increasing number of private vehicles is one of the reasons for traffic congestion. (True)

Thus, the correct answer is (d).
