The concentration of solute is greater in the environment than inside the cell. The concentration of solute is greater in the environment than inside the cell.
The concentration of solute in the environment is different from the concentration inside the cell. The concentration of solute in the environment is different from the concentration inside the cell.
The concentration of solute is greater inside the cell than in the environment. The concentration of solute is greater inside the cell than in the environment.

The correct answer is: The concentration of solute in the environment and the concentration inside the cell are at equilibrium.
The correct answer is: The concentration of solute in the environment is different from the concentration inside the cell.
To understand why, let's break down the term "isotonic" and how it relates to solute concentration.
In biology, an isotonic environment refers to a solution that has the same concentration of solutes as the solution inside the cell. This means that the concentration of solutes in the environment and inside the cell are equal.
In this case, none of the given options accurately describe an isotonic environment. Option 1 states that the concentration of solute is greater in the environment than inside the cell, which would make it hypertonic, not isotonic. Option 3 states that the concentration of solute is greater inside the cell than in the environment, which would make it hypotonic, not isotonic. Option 4 states that the concentration of solute in the environment and inside the cell are at equilibrium, which would also make it isotonic, but it is not mentioned whether they are equal or not, so it cannot be the correct answer.
Therefore, the correct answer is option 2: The concentration of solute in the environment is different from the concentration inside the cell.
