Final Answer :
D
Explanation :
Prokaryotes are believed to have evolved around 3.5 billion years ago, shortly after the formation of the Earth. This is based on fossil evidence and genetic analysis of modern prokaryotes. Option A (1 million years ago) and B (4 million years ago) are too recent, and option E (4.6 billion years old) refers to the age of the Earth itself, not the evolution of prokaryotes. Option C (1 billion years ago) is also too late considering the evidence available.
