Answer: A

Explanation:

The fault attack described involves forcing all possible incoming errors from software/operating system interfaces. The type of failure being sought is one where the application does not handle erroneous or unexpected input correctly, which can lead to crashes or other unintended behavior. Thus, an application crash when unsupported characters are pasted into an input field is a typical failure that this kind of fault attack would aim to uncover.
