You cannot devise a method which …… all possibility of errors. A. excludes B. includes C. avoids D. ignores

excludes
includes
avoids
ignores

The correct answer is C. avoids.

The word “avoids” means to keep away from or prevent something. In this case, it means that it is impossible to create a method that will prevent all errors from occurring. This is because errors can happen for a variety of reasons, including human error, hardware failure, and software bugs.

The other options are incorrect because they do not accurately reflect the meaning of the sentence. The word “excludes” means to leave something out or not include it. The word “includes” means to contain or have something as a part of it. The word “ignores” means to pay no attention to or disregard something.

In conclusion, the correct answer is C. avoids.
