Best Answer Explained in Below-:

The phrase "call on" can have multiple meanings depending on the context in which it is used. However, in the options provided, "stand in the queue" (Option D) comes closest to a relevant interpretation of "call on." In a more general sense, "to call on" someone often means to visit or make a request; however, it can also imply engaging with someone in a way that could involve taking one’s turn, much like standing in line for something.

In a different context, such as "calling on" a person in authority or someone who manages a queue, it might involve waiting your turn to address or be served by that person. Therefore, while "to visit" (Option B) might seem like a direct interpretation, "stand in the queue" contextualizes the action of waiting for one's opportunity to engage, thus capturing a more nuanced meaning of “call on” in certain situations. The other options, such as "long journey" and "former diner," do not relate to the phrase in any meaningful way, making them less accurate choices.
