   A security analyst is building a Falcon Event Search query to investigate a suspicious process that ran at a specific time. The analyst knows the exact UTC time of interest is `2024-04-05 14:30:00 UTC`. How should the analyst express this in the query to match the event's `ProcessStartTime` field?

   • AConvert the UTC time to Unix epoch seconds and use that numeric value in the query.
   • BAdd the local timezone offset to the UTC time before using it in the query.
   • CUse the `time()` function in the query to convert the string to a Unix timestamp.
   • DUse the string `2024-04-05 14:30:00` directly in the query, as Falcon automatically converts it to Unix time.
