Which of the following is a disadvantage of CAD software?

The chosen answer highlights a significant disadvantage of CAD software: the potential for software to crash during operation. This issue can lead to a loss of unsaved work, which can be frustrating and time-consuming for users. Crashes may occur due to various reasons, such as software bugs, insufficient computer resources, or power interruptions. This concern emphasizes the importance of saving work regularly and having backup systems in place.

The other options provided describe advantages of CAD software. The ability to easily modify images (first option) is one of the core benefits of using CAD, allowing for quick adjustments and iterative design processes. The second choice underscores the flexibility of working from home, which can reduce commuting costs and improve work-life balance. The last option mentions the use of recycled paper, which is typically related to sustainable practices in printing and design but does not directly pertain to the disadvantages of CAD software itself.
