Explanation:

The correct answer is option 'B' - Pre meet committee.

A committee is a group of individuals who come together to work towards a common goal or objective. In the context of this question, the responsibility of the committee is to fix the venue, date, and timing of the sports events. Let's understand why option 'B' - Pre meet committee is the correct answer.

Pre-meet Committee:
- The role of a pre-meet committee is to plan and organize the logistics and details of an event before it takes place.
- In the context of sports events, a pre-meet committee is responsible for determining the venue, date, and timing of the event.
- This committee works in advance to ensure that all necessary arrangements are made for the smooth conduct of the event.
- They consider various factors such as availability of the venue, weather conditions, availability of participants, and other logistical considerations while fixing the venue, date, and timing.
- The pre-meet committee may also be involved in coordinating with other stakeholders such as sponsors, officials, and participants to ensure their availability and participation in the event.

Other options:
- Post-meeting committee: This option is incorrect because a post-meeting committee typically works after an event or meeting has taken place. Their responsibilities may include evaluating the success of the event, gathering feedback, and making improvements for future events. However, in this question, the committee's responsibility is related to the planning and organization of the event, not the post-event activities.
- During-meet committee: This option is incorrect because a during-meet committee would be responsible for managing and overseeing the event while it is happening. Their responsibilities may include coordinating activities, ensuring the smooth flow of the event, and addressing any issues or emergencies that arise during the event. However, in this question, the committee's responsibility is related to the pre-event planning and organization.

Therefore, the correct answer is option 'B' - Pre meet committee, as they are responsible for fixing the venue, date, and timing of the sports events.
