Pairs that sum to 5 are (1,4), (2,3), (3,2), (4,1). There are 4 ways you can get that sum out of 36 possible outcomes. Assuming each outcome is equally likely, the probability of a sum of 5 is ...
The answer is C. Because, There's vertical asymptotes at 1 and -1. Vertical asymptotes are present where the x on the denominator is equal to 0. So, Both the values are 1 and -1 set are equal to the 0 in the denominator, So, They're both horizontal asymptotes. Good Luck!
