Explanation:

To determine how sucrose changes the configuration of sucrase, we analyze each option:

• "by force when under pressure": Enzyme - substrate interactions (like sucrose and sucrase) do not involve pressure - induced force - based shape change.
• "By significant trauma when they collide randomly": Enzyme - substrate binding is a specific interaction, not a random collision - induced trauma - based change.
• "By binding to the active site of the enzyme": Sucrase is an enzyme, and sucrose is its substrate. When a substrate (sucrose) binds to the active site of the enzyme (sucrase), it induces a conformational change (change in shape) in the enzyme to facilitate the catalytic reaction. This is in line with the induced - fit model of enzyme - substrate interaction.
• "By changing the pH of the solvent": Sucrose does not change the pH of the solvent to alter the enzyme's shape. The pH - related effects on enzymes are due to factors like the concentration of H⁺/OH⁻ ions, not the substrate directly changing pH.

Answer:

C. By binding to the active site of the enzyme
