Explanation : Though 'sound is audible' is true, it is a rather
insignificant or trivial reason to support the
statement 'Sound is permanent'.
Fallacy of trivial reason: a reason given
in support of a conclusion being very
insignificant in establishing the truth or falsity
of the conclusion.
Fallacy of the irrelevant reason: a reason given
in support of a conclusion being irrelevant
to the truth or falsity of the conclusion.
Fallacy of contradictory reason: a reason given
in support of a conclusion being contradictory
to the truth or falsity of the conclusion.
Fallacy of wrong assertion: a reason repeatedly
asserted as true despite being faulty.
