Which informal logical fallacy is committed in the following argument? 'The maths teacher said there was to be no talking during the test, so it is fair that Chandni had points deducted for asking to go to the washroom because she felt sick.'

The argument wrongly applies a general rule to a special case that it was never meant to cover.

The rule 'no talking during the test' is a sound general guideline aimed at preventing cheating and distraction.

Chandni's request to leave because she felt sick is a genuine exception, not the mischief the rule targets.

Deducting points treats an accidental circumstance as if the general rule applied without qualification.

Forcing a broad rule onto a case with special features is the fallacy of accident.
