Which is the odd one out among dogs, cats, apple tress and water?

Water-dogs, cats and apple trees are all living creatures. Although plants do not move or eat like animals (except venus flytraps), they are alive. Plants grow and have children - their seeds are like plant eggs, and seedlings like baby plants. Plants breathe in carbon dioxide and breathe out oxygen and eat by absorbing nutrients from the ground and from the sun. It is also possible for plants to die. water, although capable of moving down a hill and swallowing a leaky boat, is not a living creature. It does not breathe, grow or have children and cannot die because it was never alive.
