Best Answer Explained in Below-:

In the context of the conversation between Mary and Ann, it is essential to recognize the urgency of the situation. Mary is emphasizing the importance of time because Ann's train is scheduled to depart at 10:20. Given this time constraint, the most logical question for Ann to respond with is about whether she has her ticket. Without a ticket, Ann cannot board her train, making it a critical concern.

Option B, "Have you got your ticket?", directly addresses this pressing issue and highlights the immediate task Ann needs to resolve before leaving for the train station. In contrast, the other options are less pertinent given the time sensitivity of the situation. For example, while packing is important (Option A) and knowing the train's departure time is relevant (Option C), these aspects become secondary if Ann does not possess a ticket (Option B). Option D, asking about the departure location, is also irrelevant since it does not pertain to preparing for the imminent journey. Therefore, Option B is the most sensible and pressing question in the given circumstance, aligning with the urgency of the moment.
