Answer:
C. DAT-1
Explanation:
Chain of custody is applied when examining digital evidence and checking for proof that no alterations have been made to the document. It ensures that the original piece of digital evidence which could be in text, image, video, or other electronic formats, is preserved and protected from alterations. Hashing algorithms which are mathematical computations that help to condense files are applied during this procedure.
Common hashing algorithms applied, include; the message digest 4, secure hashing algorithms 1, 2, 256, 224, 512, etc. The message digest 4 is used to evaluate why a particular piece of evidence was handled by an individual. This is further authenticated by examining the fingerprint.
Explanation: Normalization is the process through which the reduction in the redundancy of data can happen.It makes the redundant in control which decrease the issue of the data integrity that appears in the good and bad database tables.
In good tables it functions for the storing of the objects in the relational database which is a difficult task and thus helps in the linking of the tables of databases.The same information level can be maintained for the different places. These are reason that normalization is important for the good table.
To create a simple chart from scratch in word
Click Insert > Chart.
Click the chart type and then double-click the chart you want.
In the spreadsheet that appears, replace the default data with your own information.
Tip: When you insert a chart, small buttons appear next to its upper-right corner. Use the Chart Elements button to show, hide, or format things like axis titles or data labels. Or use the Chart Styles  button to quickly change the color or style of the chart. The Chart Filters  button is a more advanced option that shows or hides data in your chart.
When you’ve finished, close the spreadsheet.
If you want, use the Layout Options button to arrange the chart and text in your document.
