Janith is creating a spreadsheet with the names, locations, dates, and costs of summer camps she is interested in attending. what is the most efficient way to also add pictures, camper reviews, staff information, activity schedules, and menus?

add an additional worksheet to the workbook
create new columns for each additional item
hyperlink the camp's web page to the document
research the information and outline on a word document

Hyperlink camp’s web page to the document  is the right answer.

Explanation:

Adding pictures will occupy more space, activity schedules might change time to time. So considering all these factors, it is better to go for adding hyperlink of the web page in the excel. The advantage here is that, if we keep all additional data in web, we can update content any time and the client can view at any time.

Also images are displayed best in web only. If we add additional column in excel, it might not work fine for adding pictures or menu. Even if we add additional worksheet, it might not satisfy the need.
