This problem is on Binomial distribution with the number of trials n= 5;
the number of success trials k= 3 and the probability of success at each 
individual trial of p= 0.25.


Go to the link https://stattrek.com/online-calculator/binomial.aspx

find free of charge calculator there and find  P(n=5; k=3, p=0.25) = 0.08789.


So, option (d) from the list is your answer.
