Correct Answer: Enlarge

Solution : The correct choice is the third option.

Explanation : The term compress refers to the action of reducing the size or volume of a file. To find an antonym, we need to identify a word that signifies the opposite action, namely expanding or increasing the size or volume. Enlarge perfectly fits this criterion, as it conveys the idea of making something larger.

The meanings of the other options are as follows:

• Search: This term refers to the action of looking for or seeking something.
• Trace: This term typically means to follow or track the course or direction of something.
• Turn: This term suggests making modifications or adjustments to the file.

Therefore, the right answer is enlarge .
