    Third scale means the length of the missing side of the triangle

    ok , so we already know that the biggest side is 12( because all the options given are also less than 12) so the third side should be such that , when added to 4, gives a number bigger than 12

    And 9 is the only measurement that meets that condition.

    the sum of any two sides should be bigger than the third side if the third side is 6, 6+4=10 , which is not bigger than 12 similarly 4+7=11 4+8=12 which are not bigger than 12 only when you add 9+4=13 gives a number bigger than 12
