C is not continuous. 
Continuous functions have connected graphs; this indicates that every possible value of x has a value of y associated with it.  In this case, that says that every possible radius measurement has a number of tennis balls associated with it.  The problem with this is that we cannot have a fractional part of a tennis ball, so it is not continuous.
        
                    
             
        
        
        
29/48 Can not be simplefied... Nothing will go into 48 that can also go into 29.
So 29/48 Is your final answer.
