You resurrected an old worksheet. It appears to contain most of the information that you need, but not all of it. Which step should you take next? a) Check for data you have previously hidden.
b) Make the columns wider.
c) Check that the worksheet is not Read-Only.
d) Change the format to reduce the font size.

a)

Explanation:

Since the worksheet contains most of the data that you need, there is a decent possibility that it also contains the data that you are missing. Therefore, you should check for data you have previously hidden. Sometimes, some data in a worksheet may become irrelevant in a given moment, and instead of deleting it since it may be useful later most people tend to make that data hidden. So checking for previously hidden data may be the best solution in this scenario.
