Which of the following is an example of a Handling Label?

The option "This way up" is indeed a correct example of a handling label. Handling labels are used to provide specific instructions on how to properly handle an item during transport. "This way up" clearly communicates the orientation in which the package must be kept to ensure its safety and integrity. This is particularly important for items that may be sensitive to being turned upside down or placed inappropriately.

Other options touch on important handling considerations but do not fit the strict definition of a handling label. For instance, "Handle with care" advises cautious handling but does not specify how to handle the item in terms of orientation or specific movements. "Fragile: Do not crush" indicates the item's vulnerability, suggesting it should be protected from crushing but does not provide orientation details. "Temperature Control Required" pertains to the environmental conditions needed for safe transport rather than the handling process itself. Thus, the most fitting example of a handling label is one that focuses explicitly on the manner in which the item should be oriented or treated during handling.
