Alex Fernandez recently became an insurance agent for CTC Casualty Insurance, a major insurance company. Although Alex has the support of CTC Casualty Insurance, he is working independently to track and analyze data about his insurance products and clients. He asks for your help in managing and analyzing data about his auto insurance policies.

Go to the Auto Insurance worksheet, which shows the coverage options clients can add to their insurance policies. Prepare for updating this worksheet as follows:

a$.$ Unprotect the worksheet so that you can edit the data.

b$.$ Unfreeze the first column, since the worksheet is not wide enough to scroll horizontally.

Alex wants to include the name of the insurance company on each worksheet, including the Clients worksheet, which he has hidden to keep the data private.

a$.$ Unhide the Clients worksheet.

b$.$ Group the Auto Insurance, Premiums, and Clients worksheets so that you can edit and format them at the same time.

c$.$ In cell A$1$ of the Auto Insurance worksheet, type CTC Casualty Insurance to display the name of the company on each worksheet.

d$.$ Fill cell A$1$ with Tan, Accent $2,$ Darker $50\%$ to coordinate with the company logo$,$ and then ungroup the worksheets.
