After the evolution of photosynthetic bacteria, cells with well-defined organism came into being around 2 billion years ago which formed an endosymbiotic relationship and formed multicellular organisms. this multicellular organism formed the first simple animals around 900 million years ago in water. Around 543 million years ago the Cambrian explosion took place after which first land animals and plants appeared around 465 million years ago.

Thus, the selected option is the correct answer.
