{'embryonic layers': [1, 0, 0, 0], 'cells': [0, 0, 0, 1], 'endoderm': [1, 0, 0, 0], 'diploblastic': [1, 0, 0, 0], 'tripoblastic': [1, 0, 0, 0], 'animals': [0, 0, 1, 2], 'ectoderm': [1, 0, 0, 0]}

Option 1: Diploblastic refers to animals in which the cells are arranged in two embryonic layers. This option is incorrect as the question specifically asks for animals with three embryonic layers.

Option 2: Ectoderm refers to the outermost layer of cells in the embryo. While it is one of the three embryonic layers, animals cannot be classified solely based on the presence of ectoderm. Therefore, option 2 is not the correct answer.

Option 3: Triploblastic refers to animals in which the cells are arranged in three embryonic layers. This option is the correct answer as it directly answers the question.

Option 4: Endoderm refers to the innermost layer of cells in the embryo. While it is one of the three embryonic layers, animals cannot be classified solely based on the presence of endoderm. Therefore, option 4 is not the correct answer.

In conclusion, the correct answer is option 3 - Triploblastic. Animals with cells arranged in three embryonic layers are called triploblastic.
