Introduction:
Paper spreadsheets are physical documents that are used to organize and analyze data in a tabular format. They can be a useful tool for organizing and calculating data, much like electronic spreadsheets. However, there are some advantages that electronic spreadsheets have over paper spreadsheets.

Advantages of paper spreadsheets:
1. Rows and columns: Paper spreadsheets can have rows and columns just like electronic spreadsheets. This allows for the organization and presentation of data in a structured manner, making it easier to read and analyze.

2. Headings: Paper spreadsheets can also have headings, which provide labels for each column. Headings make it easier to understand the data being presented and help in organizing and sorting the information.

3. None: This option is incorrect as it suggests that paper spreadsheets do not have any advantages over electronic spreadsheets. However, as mentioned earlier, paper spreadsheets do have some advantages such as the ability to organize data using rows and columns and the inclusion of headings.

Disadvantages of paper spreadsheets:
1. Speed: The correct answer to the question is option 'C' - Speed. Electronic spreadsheets have a clear advantage over paper spreadsheets when it comes to speed. With electronic spreadsheets, calculations can be performed instantly and formulas can be copied and applied automatically. This saves a significant amount of time compared to manually performing calculations and copying formulas on paper spreadsheets.

2. Complex calculations: Electronic spreadsheets can handle complex calculations and formulas much more efficiently than paper spreadsheets. With electronic spreadsheets, formulas can be easily entered and modified, and calculations can be performed with a high degree of accuracy. In contrast, performing complex calculations on paper spreadsheets can be time-consuming and prone to errors.

3. Storage and sharing: Electronic spreadsheets can be easily stored, shared, and accessed by multiple users simultaneously. Paper spreadsheets, on the other hand, require physical storage space and can only be accessed by one user at a time. This makes electronic spreadsheets more convenient and efficient for collaborative work and data sharing.

In conclusion, while paper spreadsheets can have many advantages such as rows and columns and the inclusion of headings, they lack the speed and efficiency of electronic spreadsheets. Electronic spreadsheets offer numerous advantages, including instant calculations, complex formula handling, and easy storage and sharing capabilities. Therefore, speed is the correct answer to the question as paper spreadsheets do not possess the same level of speed and efficiency as electronic spreadsheets.
