A) Preference for birds is significantly lower than for the other three groups, and there are no other differences among the mean preferences.
B) Dogs and cats are preferred over birds and fish, but there are no differences between the other groups.

Given the means and the context, the significant effect is that the preference for birds (M = 2.73) is notably lower than for dogs (M = 4.43), cats (M = 4.18), and fish (M = 4.07). The other groups' means are relatively close to each other, suggesting no significant differences among them, thus making option A correct.
