Answer:
You can edit the existing formula by clicking the cell in which formula is referenced, then edit the formula in the formula bar. (option c is correct)
Explanation:
This question is about how to edit the existing formula. In Excel, you can edit the formula. First, you have to click the cell in which the formula is written. Then you have to edit it in the formula bar. However, if you know and remember the formula, you can edit directly in the cell. But the best practice is to edit the formula in the formula bar.
Why other options are not correct.
- In a cell that is referenced in the formula:
The cell that is referenced in the formula does not affect the formula. Because to edit something in the referenced cell, does not guarantee to affect the formula that you want to edit. To edit the existing formula, you click the cell in which formula is written, then edit it in the formula bar.
- In the first blank cell of the worksheet
It is not necessary, that there would be a formula in the first cell. But, if there is a formula in the first cell, you should edit the formula directly in the formula bar.
You can't edit the existing formula in the status bar because the status bar is used for showing the status of actions you are doing in excel. The status bar is shown at the bottom of the excel sheet.

The correct answer: Data independence
Data independence<span> is the type of </span>data<span> transparency that matters for a centralised DBMS. It refers to the immunity of user applications to changes made in the definition and organization of </span>data<span>. Physical </span>data independence<span> deals with hiding the details of the storage structure from user applications.
</span>
The logical<span> structure of the data is known as the 'schema definition'. In general, if a user application operates on a subset of the </span>attributes<span> of a </span>relation<span>, it should not be affected later when new attributes are added to the same relation. Logical data independence indicates that the conceptual schema can be changed without affecting the existing schemas.
</span>
<span>The physical structure of the data is referred to as "physical data description". Physical data independence deals with hiding the details of the storage structure from user applications. The application should not be involved with these issues since, conceptually, there is no difference in the operations carried out against the data.</span>
