First step is just like a dummy, because we don't really know the correct answer. so pick any animal you like.
Now we get 3 question marks which means 3 of these animals are right, but they are in the wrong positions, so we can take off the 4th animal penquin.
Woo, so lucky, we've got 3 ticks (3 of them are correct). Now we need to compare these two steps to figure out which animal is incorrect, from the picture below you can see the Red Robin, the Butter Fly And the Snail are included in both steps, so if suppose the Penquin and the Fish are the wrong choices, then the Robin, the Butter Fly And the Snail(A) will become the correct. But there is another possibility which is one of these 3 are the wrong choices, then the other 2 and either the Penquin nor the Fish(B) will become the correct choices. At last we still need to try few more steps to make sure which answer is right.
First we tried B, we move out the Butter Fly, and we get two ticks. next we move the Butter Fly in agian, it become 2 Ticks and 1 Qmark, so that means possibility A is right. Now follow the 2nd step we replaced the Fish instead of Rabbit.
So this is the correct answer.
