This table shows the weights of four different objects that are sitting on the floor.

\begin{tabular}{|l|l|}
\hline
Object & Weight [tex]$(N)$[/tex] \\
\hline
1 & 35 \\
\hline
2 & 23 \\
\hline
3 & 26 \\
\hline
4 & 18 \\
\hline
\end{tabular}

A person tries to lift each object with a force of 25 N, upward. Which statement is supported by the data in the table?

A. Objects 1 and 3 will move downward, and objects 2 and 4 will move upward.
B. Objects 1 and 3 will not move, and objects 2 and 4 will accelerate upward.
C. All of the objects will move, but object 1 will accelerate the slowest.
D. None of the objects will move, but the normal force on all of the objects will increase.

To determine the movement of each object when a person tries to lift them with a force of 25 N upwards, we need to compare this applied force to the weights of each object given in the table. Here's a breakdown:

1. Object 1:
- Weight: 35 N
- Applied Force: 25 N
- Since 25 N is less than 35 N, Object 1 will not move because the applied force is insufficient to overcome the weight of the object.

2. Object 2:
- Weight: 23 N
- Applied Force: 25 N
- Since 25 N is greater than 23 N, Object 2 will move upward and accelerate because the applied force is greater than the weight of the object.

3. Object 3:
- Weight: 26 N
- Applied Force: 25 N
- Since 25 N is less than 26 N, Object 3 will not move because the applied force is insufficient to overcome the weight of the object.

4. Object 4:
- Weight: 18 N
- Applied Force: 25 N
- Since 25 N is greater than 18 N, Object 4 will move upward and accelerate because the applied force is greater than the weight of the object.

Based on the analysis for each object:
- Objects 1 and 3 will not move because their weights are greater than the applied force.
- Objects 2 and 4 will accelerate upward because the applied force is greater than their weights.

The correct statement supported by this data is:
B. Objects 1 and 3 will not move, and objects 2 and 4 will accelerate upward.

Thus, the chosen option is B.
