The number of outcomes in the sample space is 32. This includes different number of heads and tail in each toss
Since there are 5 coins, the number of tails could be
0 if we get 5 heads on all 5 coins
5 if we get 5 tails on all 5 coins
4 if we get 4 tails and 1 head on all 5 coins
Thus, the correct options are 0, 5 and 4
