Considering the RationalNumber Class, what does the following code segment do when executed? public void mystry() { if (this.numerator!= 0){ int temp= this.numerator; this.numerator= this.denominator; this.denominator= temp: }//if }//mystry Flips the RationalNumber all the time Flips the RationalNumber only if the original denominator is not equal to 0 to avoid division by 0 Elips the RationalNumber only if the original numerator is not equal to 0 to avoid division by 0 Makes the numerator and denominator similar, and thus will be reduced to 1 None of the above
