Show answer and explanation

Correct answer: (B) time spent by the transport truck in traveling between a pickup point and the disposal site with a loaded container

Explanation

In municipal solid waste collection, the **hauled container system** works in cycles: the truck drives to a loaded container, picks it up, hauls it to the disposal site, empties it, and returns the empty container.

The *haul* part of the cycle is the **travel time**, that is, the time the vehicle spends driving between the pickup location and the disposal site. In the conventional mode this includes the haul with the loaded container to the disposal site (and the return trip).

The other times are counted as separate parts of the cycle: pickup time, time at the disposal site, and driving from the depot to the first pickup. So the correct description of haul is **travel with a loaded container between the pickup point and the disposal site** (option B).
