The chronological account of a closure report:

A) explains the report topic.
B) describes problem identification,actions,and results.
C) assesses the success of a project or work.
D) summarizes most important outcomes from the reader's perspective.

A closure report typically includes a detailed account of problem identification, actions taken to address the problem, and the resulting outcomes. This information is typically presented in chronological order to provide a complete picture of how the project or work came to a close. While the report may also assess the success of the project or work, this is not always a primary focus. Additionally, while the report may summarize outcomes, this is typically done in conjunction with a more detailed description of problem identification and actions taken.
