Tristan has successfully deleted the blank row. The next thing he wants to do is increase the length of the first column.

\begin{tabular}{|l|c|}
\hline \multicolumn{1}{|c|}{ Use } & Percentage \\
\hline Space cooling & 17.5 \\
\hline Water heating & 9.5 \\
\hline Lighting & 9.2 \\
\hline Space heating & 9.1 \\
\hline \begin{tabular}{l}
Refrigerators and \\
freezers
\end{tabular} & 8.8 \\
\hline \begin{tabular}{l}
Television and related \\
equipment
\end{tabular} & 5.9 \\
\hline All other uses & 40.0 \\
\hline
\end{tabular}

How does he resize the column?

A. Move the Move Table Column marker on the ruler to the left.
B. Move the Move Table Column marker on the ruler to the right.
C. Put the cursor on the right side of the first column and drag the cursor to the left.
D. Put the cursor on the right side of the first column and drag the cursor to the right.

To increase the length of the first column, Tristan will need to modify its width. Specifically, he should do the following:

1. Move the Move Table Column marker on the ruler to the right: This action will ensure the first column becomes wider, thereby increasing its length.

So, the correct action Tristan should perform is: Move the Move Table Column marker on the ruler to the right.
