Which form of the verb correctly indicates the status of the meeting?

The choice "is" is the correct form of the verb to indicate the status of the meeting when referring to it in the present tense. Using "is" communicates that the meeting is currently happening or that its status is still relevant to the present moment.

In the context of meetings, which are often singular events, "is" effectively conveys a clear, ongoing status. This indicates to the reader or listener that the meeting is either currently taking place or is still pertinent at the time of speaking or writing.

In contrast, the other forms suggest different tenses or pluralities that do not align with the idea of a singular, present situation regarding a meeting. For example, "was" and "were" imply past status, while "are" indicates a plural subject, which is not appropriate when discussing a singular meeting status.
