Once the record is created, the next step is ______.

  1. storage

  2. retrieval

  3. utilization

  4. disposition
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

In the context of record management, once a record is created, it must be utilized for its intended purpose. Storage, retrieval, and disposition are subsequent or parallel lifecycle stages, but utilization is the primary functional step following creation.
