Discuss
Answer & Solution
Answer: Option B
Solution:
For an open control system, the following statements are generally true:

Less expensive: Open control systems are often less expensive to implement compared to closed-loop systems.
Construction is simple and maintenance easy: Open control systems are simpler in design and therefore easier to maintain.
Errors are caused by disturbances: Open control systems can be affected by external disturbances as they do not have feedback to correct deviations.

However, the statement that recalibration is not required for maintaining the required quality of the output is incorrect.

Open control systems may still require recalibration to maintain output quality, as they lack feedback mechanisms to automatically adjust for changes and disturbances.
